You are trying to put the Protestant idea of being saved into Pentecost.
The Apostles, as are all Catholics, were saved with the Baptism. Whether it was of water and the spirit, a Baptism of Desire like the good thief on the Cross or a Baptism of Blood like the martyrs.
We must account for our deeds each day. Once saved/always saved is not sound doctrine in the Catholic Church. We are all sinners — so once saved/always saved doesn’t work.
Straw Man on your part.
I am not putting “the Protestant idea” into anything. /roll eyes. You are the one divisively separating this into Protestant/Catholic.
Pentecost did not save them. They were already saved before the Day of Pentecost. Speaking with tongues did not save them. Being baptized in water did not save them (a Church of Christ belief). Believing in Jesus saved them.
Romans 10:9-10 “If thou shalt confess with thy mouth the Lord Jesus Christ, and shall believe in thine heart that God hath raised Him from the dead, thou shalt be saved.” Period.
Baptism is commanded by Christ, as a public show of your faith, a symbolic ‘death’ and ‘burial’ (immersion) and subsequent resurrection of the ‘New Creation’.
The thief on the cross was not baptized, yet Jesus said he would be with Him in paradise - THAT DAY.
I can show you scripture supporting the idea/doctrine that once you are saved/born again, you are Saved, final answer.
‘No man can pluck you from my hand’. No one, even your self.
‘Depart from me, you worker of iniquity. I never knew you.’ Notice the NEVER. Jesus didn’t say, ‘I knew you once, but you went away.’ Nor did He say “Depart, I didn’t know you long enough.’
‘That whosoever believes on Him shall have ETERNAL life.’
No one, not even Mother Theresa, can EARN Heaven on being good enough, Not Possible. We are saved by faith and THAT a gift from God, not of ourselves.
So, if we can do NOTHING to EARN it, what can we possibly do to KEEP it? It is a gift, and as far as I can tell God is no ‘Indian Giver’.
And for the argument that once saved-always saved opens the door to sinful living, that is false. Paul addressed that - Shall we sin so that Grace can abound? Heaven forbid!
A saved person, truly saved, will not willfully sin without the Holy Spirit ‘eating your lunch’.
Can you show me scripture showing that the gift of salvation can be lost?
Just my 2 cents
But it is Biblical truth.
We are all sinners — so once saved/always saved doesn’t work.
Completely invalid conclusion ...
1 John 5:13
These things I have written to you who believe in the name of the Son of God, so that you may know that you have (present active indicative) eternal life.
If you could loose eternal life ... it wouldnt be eternal.
