Protestants say they know they are saved. Some even say they know the precise day and time they were saved. Yet, if we point out a Protestant who has fallen away from the faith, other Protestants will say, "well he wasn't really saved."

And yet, he too used to proclaim that he was saved.

But as Catholics, we don't proclaim ourselves saved. We leave that judgment to God:
1 Corinthians 4:5

King James Version (KJV)
5Therefore judge nothing before the time, until the Lord come, who both will bring to light the hidden things of darkness, and will make manifest the counsels of the hearts: and then shall every man have praise of God.

Sincerely,

De Maria
