I do appreciate your sharing with me. And perhaps what I am about say belongs on another thread, but
“…a long and painful period of purification.”
Rom. 4:8, "Blessed is the man whose sin the Lord will never count against him.”.
John 19:30 “It is finished.” If purgatory exists, then it is not finished.
What is it that was finished on the Cross?
Not my salvation, since I wasn’t even
born until more than 1900 years after the Crucifixion, and I have not yet died. My salvation will be completed when I enter into Heaven, and not a moment before then.
When Jesus said, “It is finished” He wasn’t referring to our salvation, but rather, to His ultimate Passover Sacrifice. The sacrifice of Christ for our sins was completed, but we do not become “saved” until after we have entered into that Sacrifice and partaken of it, through the living of the Christian life.
“…those who willingly undergo purification during this life, by attending Confession and Holy Mass…”
Gal. 2:16, “…by the works of the Law shall no flesh be justified.”
The Sacraments are not “works of the Law” - they are the works of Jesus Christ.
Gal. 2:21, “I do not nullify the grace of God; for if righteousness comes through the Law, then Christ died needlessly.”
It is only because Christ died on the Cross, thus providing us with the Sacrifice for our sins, that the Sacraments are even possible, in the first place.
“There are some …who have never…develop sinful habits…who can go directly to Heaven without a period of purification.”
John 14:6, Jesus said, “I am the way, the truth and the life. No one comes to the Father except through me.”
Then Jesus is not the only way to the Father?
They enter into Christ through Baptism. I was not referring to people who were never baptized - we have no idea what happens to them, since as far as we can tell, they are still the property of the Devil because of Original Sin - but it is within reason that God would provide them with a way to get to Heaven that we know nothing about, since God wants
everyone to be saved, of course.
But, if someone is baptized (brought into Christ) and then never sins before his death, he would go directly to Heaven - he would be perfect in Christ.
