If Catholics left it at that we could agree but they don’t. The RCC has incorporated other demands for obtaining salvation.
There's the requirement for baptism, confession, communion, last rites, etc.
It's odd that when Jesus said that those who are going to be judged based on their works will be judged on this...
Matthew 25:35-36 For I was hungry and you gave me food, I was thirsty and you gave me drink, I was a stranger and you welcomed me, I was naked and you clothed me, I was sick and you visited me, I was in prison and you came to me.'
Jesus never said any of the things the RCC has since added itself under threat of damnation by anathema's.
Loving our neighbor and doing those works come naturally for the believer. Evidence of that is that those judged to be sheep did those things out of love for their fellow man, not to earn brownie points with God. By their questioning, it's obvious that they weren't even really aware of the fact that they were doing what God expected of them.
OTOH, those who did good works for show and appealed to them were the ones Jesus said that He never knew.
Matthew 7:21-23 21 "Not everyone who says to me, 'Lord, Lord,' will enter the kingdom of heaven, but the one who does the will of my Father who is in heaven. 22 On that day many will say to me, 'Lord, Lord, did we not prophesy in your name, and cast out demons in your name, and do many mighty works in your name?' 23 And then will I declare to them, 'I never knew you; depart from me, you workers of lawlessness.'
Obviously, the religious works don't cut it. And what's the first thing so many churches try to get people to do?
Religious works.
The Church offers grace which helps to continue to “abide in Christ”.
Salvation is God’s alone to give and He has offered it to us through belief in His Son Jesus.
Jesus has given us His Church which is guided by the Holy Spirit so that we may remain in Him and He in us.
