“The key to salvation is repentance - changing one’s life, and not abiding in the old ways but putting on Christ Jesus.”
Wow. You couldn’t have said the opposite of the Gospel more accurately.
“We Catholics have it a lot more abundantly than do evangelicals and protestants who are missing the fullness of the sacraments.”
There are no sacraments, so your point is false. The Bible does command us to baptize believers and keep the Lord’s supper in memory of Him.
“Which simply means we have more responsibility to change so as to give the example the Lord asks of us.”
Or you could start with God’s revealed Word and learn what grace is...
Funny you base all your Grace on the sacraments, but yet the concept (Catholic) of sacrament wasn’t developed for at least 1200 years after Christ.
