What are the differences between Catholics and Protestants?

The question of what separates Roman Catholicism from Protestantism touches on nearly every major point of Christian doctrine. The writers at stempublishing.com — many of whom came to faith from Catholic backgrounds or ministered in Catholic countries — address this from multiple angles.

Scripture vs. Tradition

The most fundamental divide concerns the rule of faith — the source of authority for what a Christian is to believe.

Rome places tradition on equal footing with Scripture and claims the exclusive right to interpret it. A. J. Pollock quotes an accredited Catholic source:

"HOLY SCRIPTURE has never sufficed in itself; it always stood in need of DIVINE TRADITION: for it is only by Divine Tradition that we learn that Holy Scripture is an inspired book. It is only Tradition that can give with authority and certainty the right meaning of Holy Scripture" (Catholic Belief, Very Rev. J. Faà Di Bruno, D.D., 35th edition, p. 23).

"HOLY SCRIPTURE and the TRADITION just described are both the Word of God" (Catholic Belief, p. 10).

A. J. Pollock

Pollock observes:

One stands aghast on the threshold of our enquiry at such a statement as this. The latter extract puts Romish Tradition on a level with the Word of God. The former extract, indeed, puts Tradition on a higher level than the Word of God, for it states that only by Tradition can we know that the Bible is inspired.

J. N. Darby analyses the New Testament use of the word "tradition" and concludes it means simply "a doctrine delivered," not "handed down" through institutional authority:

"Tradition" in the popular sense is in contrast with scripture; but in the passage you refer to (2 Thess. 2:15) it is either the direct word of prophecy in the church there, or the apostle's epistle. No thing handed down in the church is secured by subsequent authority.

J. N. Darby

He presses the deeper point:

If it [scripture] is received on the authority of the church, it is not believing GOD. The word of God proves itself to the conscience, and puts man by itself under the responsibility of it; because God cannot speak without man's being bound to hear and know Him, for none speaks like Him.

William Kelly summarises the contrast sharply:

Their hostility to scripture, in order to claim authority for the church both to authenticate and to interpret it, is the plainest defection from the faith. For the church is in no way the truth, but responsible to be its pillar and base. If the Queen sent a letter by the post, just think of the empty conceit of the postmaster or the postman pretending to accredit what solely depends on her majesty's sign-manual!

William Kelly

Rome also discouraged private reading of the Bible. Pollock quotes the 4th Rule of the "Index of Prohibited Books":

"Since it is manifest by experience that if the Holy Bible in the vulgar tongue be suffered to be read everywhere without distinction, more evil than good arises... whosoever shall presume to read these Bibles, or have them in possession without such faculty, shall not be capable of receiving absolution for their sins, unless they have first given up their Bible to the ordinary."

Justification by Faith Alone

The doctrine that ignited the Reformation — and remains the sharpest doctrinal divide — is how a sinner is made right with God. Andrew Miller narrates Luther's breakthrough, when the vicar-general Staupitz assured him:

that he was entirely mistaken in supposing that he could stand before God on the ground of his works or his vows, that he could only be saved by the mercy of God, and that mercy must flow to him through faith in the blood of Christ.

Andrew Miller

Luther had spent years in monastic rigour trying to earn acceptance with God. Miller writes:

He was attempting to do the work for himself which Christ had done for him — and done perfectly. And are not thousands in the present day doing the very same thing that Luther did, only less sincere, less earnest, less self-denying?

Kelly points out that the Council of Trent formally rejected this doctrine:

The Council of Trent (Sess. vi. cap. 9) nullifies this, the simple and certain word of truth, the gospel of our salvation; and in Can. ix. it anathematises any one who says that the ungodly man is justified by faith alone. They are, therefore, false witnesses and adversaries of the faith.

Darby addresses his Catholic readers directly:

The Lord Jesus, by the one sacrifice of Himself once offered, has totally and eternally put away sin, so that it shall never be imputed at all to those that believe on Him, and that every repentant sinner who comes to Him is justified from all things, is accepted of God in Christ, with all the love He bears towards the Lord Jesus, for whose sake He does so accept us.

The Mass vs. the Once-for-All Sacrifice

Rome teaches that in the Mass, Christ is offered anew as a propitiatory sacrifice for the living and the dead. Darby writes:

Christ, the Spirit of God has declared, has put away sin by the sacrifice of Himself: if He has, what need of any other sacrifices? He hath made an end of sin, says Daniel, and brought in everlasting righteousness. But in your sacrifices there is a remembrance made of sin as not put away; for if Christ has reconciled us to God, and expiated sin for us, what is the repeated sacrifice for?

He quotes Hebrews 10:17-18:

"Their sins and iniquities I will remember no more. Now, where there is remission of these, there is no more an oblation for sin."

Kelly calls it a matter of fundamental principle:

No article of Popery is more sacred than that which is professed in the Creed of Pope Pius IV, that in the mass is offered to God a true, proper, and propitiatory sacrifice for the living and the dead. Necessarily then the simple and complete efficacy of Christ's sacrifice is disbelieved. For if His blood really cleanses from all sin, it is dishonoured and in effect denied by supplementary sacrifices.

Transubstantiation

The doctrine that the bread and wine are physically transformed into Christ's body and blood. Miller traces its history:

The dogma nowhere occurs in the writings of either the Greek or Latin Fathers. The first trace of it is to be found in the eighth century... It was then placed among the settled doctrines of the church of Rome [at the Fourth Lateran Council in 1215].

Darby offers a theological refutation:

There is no such Christ in existence as that signified by the sacramental institution. There is a glorified Christ with a body in heaven, but this is a given body and shed blood. That is, it is a dead Christ we, in the power of resurrection, recognise and feed on... But there is no dead Christ now.

If the blood be thus united to the body, there is no redemption at all. It is the blood "shed" which is redemption; and therefore we are called to "drink" it as a separate thing.

Priesthood

Rome maintains a distinct priestly class with power to offer sacrifice and grant absolution. Darby contrasts this with the New Testament, quoting Hebrews 7:

"The others indeed were made many priests, because by reason of death they were not suffered to continue; but this, for that he continueth for ever, hath an everlasting priesthood, whereby he is able also to save for ever them that come to God by Him, always living to make intercession for us."

He concludes:

In a word, Jesus Christ is the Priest of the Christian church and its sacrifice; nor is there the least ground whatever given by God, for any man to assume the character of a priest, that is a sacrificer; and whoever does it, does it on his own authority and in opposition to God and His Christ.

The One Mediator and the Worship of Mary

Scripture declares there is "one mediator between God and man" — Christ Jesus. Rome multiplied mediators through the intercession of saints, angels, and above all, the Virgin Mary. Kelly writes:

The Romish creed consecrates natural feeling without the least warrant and in the grossest way, against the faith of God's elect in the mediation of the Virgin, of angels, and of saints. Scripture is not plainer in the O.T. for the unity of God than in the N.T. for "one mediator between God and man" — Christ Jesus.

Miller documents how veneration of Mary grew:

Before [the fourth century], there is no trace of the worship of Mary... In the fifth century, images and beautiful paintings of the virgin, holding the infant Jesus in her arms were placed in all the churches. Thus introduced she rapidly rose into an object of direct worship.

He quotes from Catholic books of devotion:

"Holy Mary, Mother of God, pray for us sinners now, and in the hour of death, Amen."

"Hail, holy Queen, Mother of mercy, our life, our sweetness, and our hope!"

And from the Romish Breviary:

"If the winds of temptation arise, if thou run upon the rocks of tribulation, look to the star, call upon Mary... in dangers, in difficulties, in doubts, think upon Mary, invoke Mary."

Purgatory

Miller traces the doctrine of a purifying fire after death to Gregory the Great (c. 600 AD) and quotes the Council of Trent:

"There is a purgatory, and the souls detained there are assisted by the suffrages of the faithful but especially by the acceptable sacrifice of the Mass."

Against this he sets plain New Testament testimony:

"Absent from the body, present with the Lord." ... "Today shalt thou be with Me in paradise." ... "Having a desire to depart, and to be with Christ; which is far better."

Kelly identifies the theological root:

They have invented an unscriptural, fabulous, purgatory, owing to the same blindness as to the efficacy of Christ's sacrifice. For though they allow that His blood meritoriously avails for the justification of the faithful, they hold... that all others must go into that future prison till they have paid the last farthing.

Indulgences

Out of purgatory grew the sale of indulgences. Miller writes:

It promises remission of sins without repentance; and, even on Catholic ground, its wickedness is manifest. It supersedes the penitential exercise of the individual; it dissolves the whole discipline of the church; it offers for a sum of money the pardon of all sins committed, a license for sins to be committed.

Papal Authority and Infallibility

Kelly examines the scriptural texts cited for papal supremacy:

"Thou art Peter (stone) and upon this (not stone but) rock I will build my church." On that believed and confessed truth He would build His church... The inspired word distinguishes in the strongest way between him who was but a stone, and the rock on which Christ builds His assembly. Romanism confounds it all in order to exalt, not Christ, but Peter.

Darby observes:

Romanists are not agreed what the rule is. Ultramontanes hold the Pope infallible, Cismontanes hold he is not. Many, as the Councils of Constance and Basle, hold that they had authority to act independently of and superior to the Pope. At the time of the former there were two Popes. The Council deposed them and chose another.

Confession and Absolution

Miller traces the formal establishment of auricular confession:

No definite law on the subject was laid down by the church till the beginning of the thirteenth century. In the year 1215, under the pontificate of Innocent III., the practice of auricular confession was authoritatively enjoined by the fourth Council of Lateran upon the faithful of both sexes at least once a year.

Scripture directs confession to God: "If we confess our sins, He is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness" (1 John 1:9).

The Headship of Christ

Kelly identifies the deepest issue:

In scripture the truth is plain. The church of God knows but one Head, even Christ in heaven. Earthly head there is none if we hear God's word. Not only is there no such anomaly as two heads of the one body of Christ; but the invariable teaching of divine revelation is incompatible with such an earthly incumbrance.

Across all these points, the differences reduce to a single question: Is the work of Christ sufficient, or does it require human supplement? Rome says the sacrifice of Christ must be repeated in the Mass, His priestly mediation supplemented by earthly priests, His intercessory work shared with Mary and the saints, His Word authenticated and interpreted by the Church, and the cleansing power of His blood completed by purgatorial fire. The answer pressed from Scripture is that Christ's work is finished, His priesthood unchangeable, His mediation sole and sufficient, and His Word self-authenticating by the power of the Holy Spirit.

As Darby put it: "By one oblation He hath perfected for ever them that are sanctified... Now, where there is remission of these, there is no more an oblation for sin."
