To know Jesus is to be BOTH Christian and Catholic.
You can't become a Christian by someone dropping water on you...It's a change of heart...It is trusting Jesus for your future...People are not Christians just because they are Catholic according to God in the scriptures...
To be a follower of Christ is to be a Christian.
To belong to the Catholic church is to be Catholic.
The two are not synonymous terms.
Christian ≠ Catholic.
Catholic ≠ Christian.
Follower of Christ = Christian. Some of whom may belong to the RCC.
