forthright:
How do we reconcile the teaching that purgatory is a process by which we are perfectly purified and made ready to enter heaven with 1 Corinthians 15:50 and following that seems to indicate we are made perfect instantly and not through a process?
I would very strongly suggest that you contact
The Bible Christian Society and get their FREE CD on
The Rapture and the Bible in which John Martignoni talks about just this thing. The fact is that this passage does tie in with the end times passages.
Let’s have a look at it for context:
50: I tell you this, brethren: flesh and blood cannot inherit the kingdom of God, nor does the perishable inherit the imperishable.
51: Lo! I tell you a mystery. We shall not all sleep, but we shall all be changed,
52: in a moment, in the twinkling of an eye,
at the last trumpet. For the trumpet will sound, and the dead will be raised imperishable, and we shall be changed.
53: For this perishable nature must put on the imperishable, and this mortal nature must put on immortality.
54: When the perishable puts on the imperishable, and the mortal puts on immortality, then shall come to pass the saying that is written: “Death is swallowed up in victory.”
55: “O death, where is thy victory? O death, where is thy sting?”
56: The sting of death is sin, and the power of sin is the law.
57: But thanks be to God, who gives us the victory through our Lord Jesus Christ.
58: Therefore, my beloved brethren, be steadfast, immovable, always abounding in the work of the Lord, knowing that in the Lord your labor is not in vain. (Emphasis mine)
Now the key to the answer to their assertion is in the parts I have bolded above. What exactly does it say? “
at the last trumpet. For the trumpet will sound, and the dead will be raised imperishable,” Now, is there any other verse that clarifies when this happens (We Catholics should find this one easy because the answer is in one of our favorite passages of the New Testament…John 6.)
John 6:38: For I have come down from heaven, not to do my own will, but the will of him who sent me;
39: and this is the will of him who sent me, that I should lose nothing of all that he has given me, but raise it up
at the last day.
40: For this is the will of my Father, that every one who sees the Son and believes in him should have eternal life; and I will raise him up
at the last day."
41: The Jews then murmured at him, because he said, “I am the bread which came down from heaven.”
42: They said, “Is not this Jesus, the son of Joseph, whose father and mother we know? How does he now say,
I have come down from heaven'?" 43: Jesus answered them, "Do not murmur among yourselves. 44: No one can come to me unless the Father who sent me draws him; and I will raise him up **at the last day.** 45: It is written in the prophets, And they shall all be taught by God.’ Every one who has heard and learned from the Father comes to me.
46: Not that any one has seen the Father except him who is from God; he has seen the Father.
47: Truly, truly, I say to you, he who believes has eternal life.
48: I am the bread of life.
49: Your fathers ate the manna in the wilderness, and they died.
50: This is the bread which comes down from heaven, that a man may eat of it and not die.
51: I am the living bread which came down from heaven; if any one eats of this bread, he will live for ever; and the bread which I shall give for the life of the world is my flesh.”
52: The Jews then disputed among themselves, saying, “How can this man give us his flesh to eat?”
53: So Jesus said to them, "Truly, truly, I say to you, unless you eat the flesh of the Son of man and drink his blood, you have no life in you;
54: he who eats my flesh and drinks my blood has eternal life, and I will raise him up
at the last day.
When does Jesus plainly say that the resurrection of the dead comes about? (Hint: If ya can’t find it up there in all those repetitions of bolded texts [again for my own emphasis] then you’ll be easy pickin’s for non-Catholic evangelism.

)
BTW, that passage has nothing whatever to do with the condition of one’s soul…it’s about the resurrection of the physical bodies of believers.
Context is EVERYTHING.

Pax tecum my friend!
