Ash Wednesday, etc, - they can all be discussed at any time. Any time is a good time to discuss the Word of God.
Secondly, I am speaking of Acts chapter 2:4 (what is recorded in Acts - that Jesus spake before Acts 2:4), and the events that occured before the Apostle Peter preached and 3000 were converted.
Again, were Peter and those who had assemebled together - were they saved before the Day of Pentecost? Were they already believers before they spake with other tongues, or did they all get saved (and thus form the body of Christ) 5 hours, 5 minutes or even 5 seconds before they spake with tongues?
And the people who listened to the apostles preach were from many countries. Each heard the apostles in their own language. The people converted on Pentecost were not the same as the apostles and a few other believers in the Upper Room when tongues of fire came to rest over them, and people assembled outside of the building because they heard a mighty wind — the Holy Spirit.
PS. Keeping topics timely helps everyone, but of course, anything can be posted at anytime.
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.
