Are Catholics Christians?
"Are Catholics true Christians, or is Catholicism a different religion?"
The Short Answer
Catholics are the original Christians. The term 'Christian' was first used in Antioch (Acts 11:26) for followers of Christ in communion with the apostles—what became the Catholic Church. We believe in the Trinity, Christ's divinity, His death and resurrection for salvation, and Scripture as God's Word.
Quick Overview
Ask yourself: Was there Christianity before the Protestant Reformation in 1517? Of course! For 1,500 years, virtually all Christians were Catholic (or Eastern Orthodox, which is very similar). We believe Jesus is God, died for our sins, and rose again. We believe in the Trinity. We believe the Bible is God's Word. We believe we're saved by grace through faith. These are the core beliefs that define Christianity. The Church Fathers, the councils that defined the Trinity and the divinity of Christ, the monks who preserved the Bible—all from the same Church. This isn't a deviation from Christianity; it's the original Christianity.
Biblical Evidence
What the Scriptures say
"And they conversed there in the church a whole year: and they taught a great multitude. And it was at Antioch that the disciples were first called Christians."
Why This Matters
The name 'Christian' was first applied to believers at Antioch - a church founded by the apostles and in communion with Peter and Paul. This church was 'Catholic' (universal).
"For I delivered unto you first of all, which I also received: how that Christ died for our sins, according to the scriptures: And that he was buried: and that he rose again the third day."
Why This Matters
We believe and profess this central Christian gospel: Christ died for our sins and rose again. This is the heart of Christianity.
"In the beginning was the Word: and the Word was with God: and the Word was God... And the Word was made flesh and dwelt among us."
Why This Matters
Catholics affirm the divinity of Christ and the Incarnation. The Council of Nicaea, attended by Catholic bishops, defined this essential Christian doctrine.
What the Church Teaches
Official Catholic doctrine
The Catechism affirms all essential Christian beliefs: The Trinity (CCC 232-267), Christ's divinity (CCC 464-469), the Incarnation (CCC 461-463), Christ's redemptive death (CCC 599-618), the Resurrection (CCC 638-658), salvation by grace through faith (CCC 1987-2005), and Scripture as God's inspired Word (CCC 105-108). These are the defining beliefs of Christianity. The Catholic Church formulated the Nicene Creed, compiled the Bible, and defined doctrines like the Trinity that all Christians accept. To call Catholics non-Christians is to say Christianity didn't exist before the Protestant Reformation.
