Before the perfect comes, Paul's speech, knowledge, and understanding were like a child's. After the perfect comes, he will be like an adult in his speech, knowledge, and understanding. He says now we see through a glass darkly. Now we know in part, but they we shall know as we are known.
Paul also writes other things that occur in the 'now.'-- Now abideth faith, hope, and charity. Right now, we have the hope of the resurrection. In the future, at Christ's return, that hope will be fulfilled.
So chapter 13 tells us about tongues and prophecy and the coming of the perfect. Chapter 14 tells us how to use tongues (with interpretation) and prophecy in an orderly manner in the assembly to edify one another. Chapter 15 tells us of the resurrection which occurs 'at His coming.'
This viewpoint fits the internal argument in the book. There is a 'long thought' that runs throughout the epistle.
But there is nothing in the epistle that leads to this conclusion that Paul is referring to a completed canon when he writes 'that which is perfect.' The Bible is about Jesus. The Bible is not about the Bible. (Ooo dat's good. Maybe I could put that on a bumper sticker.)
Nice try but NO.
The 'perfect which is to come' is nothing more than LOVE which Christ brings with Him in our hearts. Loving one another is 'being perfected in Love' and this is what is referred to as knowing God as we are known. John reiterated this simple fact here:
1 John 4:
7 Beloved, let us love one another, because love comes from God. Everyone who loves has been born of God and
knows God.
8Whoever does not love does not know God, because God is love.
9This is how God’s love was revealed among us: God sent His one and only Son into the world, so that we might live through Him.
10And love consists in this: not that we loved God, but that He loved us and sent His Son as an atoning sacrifice for our sins.
11Beloved, if God so loved us, we also ought to love one another.
12No one has ever seen God; but if we love one another, God remains in us, and His love is perfected in us. 13By this we know that we remain in Him, and He in us: He has given us of His Spirit.
14And we have seen and testify that the Father has sent His Son to be the Savior of the world.
15If anyone confesses that Jesus is the Son of God, God abides in him, and he in God.
16And we have come to know and believe the love that God has for us. God is love;
whoever abides in love abides in God, and God in him. 17In this way, love has been perfected among us, so that we may have confidence on the day of judgment; for in this world we are just like Him.
And when was this perfect love to come?
Heb 10:36 You need to persevere, so that after you have done God’s will, you will receive what He has promised. 37
For, “In just a little while, He who is coming will come and will not delay.
There's no amount of twisting and turning that would make the above mean 21st century and counting, it was just 1st century when these things were accomplished. If anyone speaks meaningless words today, it is straight from their head, let them not associate God in their own worldly things. Miracles and signs continued but it is not from God. Hence:
Matt 7:
21Not everyone who says to Me, ‘Lord, Lord,’ will enter the kingdom of heaven, but only he who does the will of My Father in heaven.
22Many will say to Me on that day, ‘Lord, Lord, did we not prophesy in Your name, and in Your name drive out demons and perform many miracles?’
23Then I will tell them plainly, ‘I never knew you; depart from Me, you workers of lawlessness!’
It is actually the opposite; those who will make it to heaven will be wondering how they made it. This is what the Lord says:
"..i was found by those who did not seek me"
