Christian is a broad term for those who believe and follow the teachings of Jesus. Catholicism is a sect of Christianity. More simply, they are a type of christian who are suppose to have, or follow, a similar interpretation of the teachings of Jesus. So basically, not all Christians are Catholic, but all Catholics are Christians.

Tofu is right... being a Catholic is being a Christian. Christianity in essence, is a religion with different sects including Catholicism.... I am a Christian, but not a Catholic. We are being taught of Jesus Christ's teachings, hence we are called Christians. :)

Hmmm... I could have so much fun with this one.... I'll shut my mouth. 8)

Actually is the same, Jesus never make some different (Catholic or Christian) but during time peoples make some rule rules developed in because human and yeah, all Catholics are Christian and Christians are not always Catholics
