You love your James 2, don’t you?
Read James 2:10
“For whoever keeps the law but fails in one point has become guilty of all of it.”
And then refers to the Ten Commandments so you can’t use that ‘ceremonial law’ out.
ALL sin is serious sin. Every sin from murder to the impure thought of just a moment.
You think you can achieve that level of perfection?
When I was a catholic, that is about what I was taught, that if I led a good enough life, it was possible I could earn my way into heaven, but I wouldn’t know till the moment I died. I hope no one comes along, and tries to tell me that’s not what the Catholic Church teaches. Hogwash. It is what I was taught.
Deep in my heart, I knew I didn’t measure up, so I gave up, and ate, drank, and was merry. Then I met some guys associated with the Navs. Now, I know I still don’t measure up, but now I sing, “There He stands the mighty conquerer, since He rent the veil in two.” There is no way, the rending of the veil was accidental. No way. See you in the clouds bros. 👍😁
The Bible disagrees:
If anyone sees his brother sinning, if the sin is not deadly, he should pray to God and he will give him life. This is only for those whose sin is not deadly. There is such a thing as deadly sin, about which I do not say that you should pray. All wrongdoing is sin, but there is sin that is not deadly. (1 John 5:16-17)You think you can achieve that level of perfection?
No, but it is important that, by God's grace, I try the best that I can. When I fail I have recourse to the sacrament of Penance where I can have my sins forgiven, as Jesus tells us. The residue for any remaining sins God will cleanse in Purgatory. It is he who will make me perfect.
