Lel, circumcision is not needed coz Christ is here. Read romans.

There's a Catholic group, you can find your favor there. Ps: I'm not even interested to discuss there coz I'm not a roman Catholic.

Saved is by the blood of Christ, by faith. What's is faith? Faith is the ability to believe, given by God. By faith we can fulfill the commandment because Christ fulfilled it already.

You sounds like a non perfect Christian unless he's perfect in this life he's not saved. That's not justification by faith, that's perfectionism which we will never attain in this life, even great spiritual being still can sins. But since we are Christian we should be able to show good fruits or change in our life. But the good deeds does not justify us. It is because by faith through Christ we can have those good deeds aka fruits.

I'm not siding which one, I just state what it means by justification by faith, it is not like once you believed you can sin or still be saved, that should not be a Christian's attitude.

A roman Catholic can also be a calvinists? As I know many rc didn't read their bible

I'm a protestant Christian

Why don't you ask there is a reformation. Rc and protestant view of the doctrine is different. Eg. we don't pray to the St, we don't have pope etc..

When we discuss other non baptisms doctrine you will say I'm of Presbyterian.
