Protestant and Catholic: What's the Difference?

Ask a serious Protestant today what is the biggest threat to orthodox Christianity today, and he might mention cultural hostilities, the sexual revolution, or nominalism in our churches. But if you would have asked a Protestant the same question a hundred years ago, he would have almost certainly mentioned the Roman Catholic Church. Until fairly recently, Protestants and Catholics in this country were, if not enemies, then certainly players on opposing teams.
Today, much of that animosity has melted away. And to a large extent, the thaw between Protestants and Catholics has been a good thing. Sincere Protestants and Catholics often find themselves to be co-belligerents, defending the unborn, upholding traditional marriage, and standing up for religious liberty. And in an age that discounts doctrine, evangelical Protestants often share more in common theologically with a devout Roman Catholic steeped in historic orthodoxy than they do with liberal members of their own denominations. I personally have benefited over the years from Catholic authors like G. K. Chesterton, Richard John Neuhaus, and Robert George.
And yet, theological differences between Protestants and Catholics are still wide and in places very deep. As the 500th anniversary of the Reformation draws near, it’s important to be conversant with some of the main issues that legitimately divide us, lest we think all the theological hills have been laid low and all the dogmatic valleys made into a plain.
Below are a few of the main points that still separate Catholics and Protestants. Of course, many Roman Catholics may not believe (or even know) what their formal theology states. But by seeking to understand official church documents we can get a good idea of what Catholics are supposed to believe and see how these differ from traditional Protestant beliefs (unless otherwise noted, quotations are from the Catechism of the Catholic Church).
Since Vatican II, the Catholic Church has softened its stance toward Protestants, calling them "estranged brothers." Nevertheless, to be a part of the church in its fullness one must be immersed in the Roman Catholic system of sacraments, orders, and under the authority of the Pope. "Fully incorporated into the society of the Church are those who . . . are joined in the visible structure of the Church of Christ, who rules here through the Supreme Pontiff and the bishops."
Further, the Pope is considered infallible when he speaks ex cathedra (from the chair); that is, when he makes official doctrinal pronouncements.
The Catholic Church also has seven sacraments instead of two--Eucharist (or Lord's Supper) and baptism like Protestants, and then penance, holy orders, marriage, confirmation, and last rites.
Catholics have a larger biblical canon. In addition to the 66 books in the Protestant Bible, Catholic Bibles include the Apocrypha, with books like Tobit, Judith, 1 and 2 Maccebees, Sirach, and Baruch. Catholic teaching also elevates tradition more than Protestants do. Granted, many evangelicals suffer from ignoring tradition and the wisdom of the past. But Catholic theology goes beyond just respecting the past; it sacralizes it. "Both Scripture and Tradition must be accepted and honored with equal sentiments of devotion and reverence," the Catechism states.
Likewise, the Magisterium has the authority to make definitive interpretations. "The task of giving an authentic interpretation of the Word of God, whether in its written form or in the form of Tradition, has been entrusted to the living, teaching, office of the Church alone . . . to the bishops in communion with the successor of Peter, the Bishop of Rome." The issue of authority continues to be the biggest practical divide between Protestants and Catholics.
Central to the Catholic faith is the Mass (their worship service), and central to the Mass is the celebration of the Eucharist. Catholics believe that bread and wine are transubstantiated into the actual, physical body and blood of Jesus Christ.
The elements are offered as a sacrifice from the church and a sacrifice of Jesus Christ's work on the cross. This is not simply a remembrance of Christ's sacrifice, but the same atoning work: "The sacrifice of Christ and the sacrifice of the Eucharist are one single sacrifice . . . the sacrifice [of the Eucharist] is truly propitiatory."
Catholics teach that "justification is conferred in Baptism." The waters of baptism wash away original sin and join us with Christ. Baptism is not merely a sign and seal of grace, but actually confers saving grace.
Mary is not only the Mother of Christ, but the Mother of the church. She was conceived without original sin (the immaculate conception) and at the end of her earthly life "was taken up body and soul into heavenly glory, and exalted by the Lord as Queen over all things" (assumption). She intercedes for the church, "continues to bring us the gifts of eternal salvation," and is "a mother to us in the order of grace."
Mary was more than just the faith-filled mother of Jesus: "The Blessed Virgin is invoked in the Church under the titles of Advocate, Helper, Benefactress, and Mediatrix."
Those who die in God's grace, but still imperfectly purified, are assured of eternal life, but must first undergo purification in purgatory. Because of the presence of this intermediate state, the Catholic Church has developed the practice of prayer for the dead. "The Church also commends almsgiving, indulgences, and works of penance undertaken on behalf of the dead."
Concerning the salvation of those who do not hear the gospel, the Catholic Catechism is committed to inclusivism: "Those who, through no fault of their own, do not know the Gospel of Christ or his Church, but who nevertheless seek God with a sincere heart, and, moved by grace, try in their actions to do his will as they know it through the dictates of their conscience--those too may achieve eternal salvation."
It is not really fair to say "Catholics teach that you can earn your salvation." That may be what many Catholics believe, but the official teaching of Rome is more nuanced, though still a long way off from the Reformation understanding sola gratia. The Catechism summarizes: "Since the initiative belongs to God in the order of grace, no one can merit the initial grace of forgiveness and justification, at the beginning of conversion. Moved by the Holy Spirit and by charity, we can then merit for ourselves and for others the graces needed for our sanctification, for the increase of grace and charity, and for the attainment of eternal life."
Catholic teaching rejects the Protestant doctrine of imputed righteousness. The question is this: is the righteousness whereby we are forgiven and made right with God a righteousness working in us or a righteousness reckoned to our account? Catholics say the former, Protestants the latter. According to Catholic teaching, justification is more than God's declaration of our righteousness based on Christ's work, it is also a renewal of the inner man and reconciliation with God. Of course, these are good things too, but Catholics make them present in and through justification, rather than by faith alone.
The Council of Trent, from the 16th century Catholic counter-reformation, declares: "If anyone says, that men are justified, either by the sole imputation of the justice of Christ, or by the sole remission of sins, to the exclusion of grace and charity that is poured forth in their hearts by the Holy Ghost, and is inherent in them; or even that the grace, whereby we are justified, is only the favor of God: let him be anathema." While individual Protestants and Catholics may work to find common ground on justification, the official teaching of the Roman Church is still opposed to any notion of an imputed righteousness through faith alone.
Should Catholics and Protestants treat each other decently and with respect? Of course. Will we labor side by side on important moral and social matters? Quite often. Can we find born-again Christians worshiping in Catholic churches? I’m sure. But are the disagreements between Protestants and Catholics, therefore, negligible? Hardly. The differences still exist, and they still matter.
Sanctify us by your truth, O Lord; your word is truth.
