I’ve always had a question for someone who says “I’m already saved.”
What happens if you commit a mortal sin and are not forgiven?
OSAS doesn’t work for me. I know I am a sinner, and I constantly must seek forgiveness.
Salvation, I know I am a sinner, too, and must always ask for forviveness.
One thing that most of your Catholic friends don’t understand is that we believe in the same truth.
Jesus is the one and only son of God, that he was sent to die on the cross to forgive us of our sins, and that those who don’t believe in this will perish.
Believing this with all of my heart is how I know that I am saved.
Being asked if I believe in three gods, and other stupid uneducated questions, was insulting.
“OSAS”
I think that there is a difference in interpretation, and ritual.
We don’t have infant Baptism because we don’t believe infants to be able to determine that they are saved.
Our Baptism is for those who believe in my post above, and have determined on their own that they are saved.
To publicly and openly proclaim that one is saved, and follow through with a voluntary Baptism, is a huge testimony to one’s faith.
Maybe that helps?
