When your entire post is just one big, word-for-word swipe from the footnotes of the New American Bible, you should acknowledge that the sentences you are posting were written by someone else...
Regardless, none of your post (lifted verbatim from footnotes in the New American Bible) changes the fact that Paul tells us we can do nothing to earn our salvation; it is all of mercy, and not debt.
But to him that worketh not, but believeth on him that justifieth the ungodly, his faith is counted for righteousness." -- Romans 4:4-5"Now to him that worketh is the reward not reckoned of grace, but of debt.
I have frequently acknowledged that my quotes are from the NAB. I freely say to the world that the Church is the pillar of truth, not some power hungry tyrant who murdered many in Geneva. If it was not clear to the heathen that this is so, then I apologize for not making it clear this time.
We Christians do not say that we either merit (on our own) or earn our salvation. I suppose that those posts have as little relevance as the four Gospels do to the Reformed.
