Salvation
Do Catholics Believe in Purgatory?
Catholics believe in purgatory — a final purification after death for those already saved. Most other traditions in our comparison do not teach it, viewing it as lacking clear scriptural warrant. The full page shows how each of the six traditions defines it, in its own words.
Compare 6 traditions →What Must I Do to Be Saved?
All six traditions agree that salvation comes by God's grace through Jesus Christ, but they describe how a person receives it differently — from a decisive moment of faith, to baptism, to a lifelong journey of transformation. They also differ on what role, if any, our response and perseverance play. Compare each tradition's account on the Salvation page.
Compare 6 traditions →What Is Justification by Faith?
Justification is God's act of declaring — or making — a sinner righteous through Christ. Traditions agree it is by grace through faith, but differ on whether justification is a one-time legal declaration or an ongoing renewal, and on how faith, works, and baptism relate. The Justification page compares all six positions.
Compare 6 traditions →Can You Lose Your Salvation?
Traditions disagree: some teach that true believers are eternally secure and cannot lose salvation, while others teach that salvation can be forfeited through persistent sin or unbelief. The divide reflects different readings of assurance and perseverance. See how each tradition explains it on the Eternal Security page.
Compare 6 traditions →What Is Predestination?
Predestination is the teaching that God has foreordained who will be saved. Traditions range from strong views of God’s sovereign election to views emphasizing human free response and God’s foreknowledge. The Predestination page lays out each tradition’s official teaching.
Compare 6 traditions →Sacraments
Is Baptism Necessary for Salvation?

Compare 6 traditions →Should Babies Be Baptized?
Some traditions baptize infants, seeing baptism as God's covenant sign extended to children, while others baptize only those old enough to profess faith. The practice follows each tradition's understanding of what baptism does. Compare all six on the Baptism page.
Compare 6 traditions →What Is Transubstantiation?
Transubstantiation is the Catholic teaching that the bread and wine become Christ's body and blood while retaining their appearance. Other traditions describe Christ's presence in communion differently — as a spiritual presence, a memorial, or a mystery. See the six positions on the Communion page.
Compare 6 traditions →Do You Have to Confess to a Priest?
Catholics and Orthodox confess sins to a priest as part of the sacrament of reconciliation; other traditions practice confession directly to God, sometimes with pastoral counsel. The differences reflect how each tradition understands priestly authority and forgiveness. Compare on the Confession page.
Compare 6 traditions →Mary & the Saints
Do Catholics Worship Mary?
Catholics honor Mary with special devotion but distinguish this from the worship owed to God alone — a distinction Protestant traditions dispute. Most Protestant traditions in our comparison honor Mary as the mother of Jesus but do not practice Marian devotion or teach the Assumption. The Mary page presents each tradition’s teaching in its own words.
Compare 6 traditions →Why Do Catholics Pray to Saints?
Catholics and Orthodox ask saints in heaven to pray for them, seeing it as communion with the whole church. Most Protestant traditions reject the practice, teaching that prayer is directed to God alone through Christ. Compare all six views on the Saints & Intercession page.
Compare 6 traditions →Scripture & Authority
What Is Sola Scriptura?
Sola scriptura — 'Scripture alone' — is the Reformation teaching that Scripture is the final authority in matters of faith. Catholics and Orthodox pair Scripture with sacred Tradition and the church's teaching authority, while evangelical traditions hold Scripture as supreme in varying degrees. The Scripture & Tradition page compares the positions.
Compare 6 traditions →Who Decides What the Bible Means?
Catholics and Orthodox look to the church and its bishops to authoritatively interpret Scripture; Protestant traditions emphasize Scripture's clarity and the believer's responsibility, guided by pastors, confessions, and the Spirit. The Scripture & Tradition page shows how each tradition answers.
Compare 6 traditions →End Times
What Is the Rapture?
