Yes context is the key, when it’s correct.
The Revelation to John
In the beginning God had said of marriage, Gen 2:24 “Therefore a man … cleaves to his wife, and they become one flesh.” Jesus assured us, Jn 6:56 “He who eats my flesh and drinks my blood abides in me, and I in him.” God prepared us first through natural marriage and then through the Holy Eucharist for the supernatural marriage to come at the end of time, Rev 20:7 “For the marriage of the Lamb has come, and his Bride [the Church] has made herself ready; it was granted her to be clothed in … the righteous deeds of the saints.” The Holy Eucharist, through which Christ abides in us and we in Him, will be our wedding feast. Rev 19:9 “Blessed are those who are invited to the marriage supper of the Lamb.”
How you come up with this is a leap of imagination.
For the very chapter you quoted from 1 Corinthians keeps stating bread, and cup.
Now all references to marriage is the Eucharist?
What is the stated Gospel of Christ the apostles preached and proclaimed?
Also, at the Last Supper were the disciples eating the literal body of Christ and drinking the literal blood of Christ while He stood there before them?
Rev 19:9 “Blessed are those who are invited to the marriage supper of the Lamb.”
Sure doesn't sound like any FEAST I've ever been invited to!
Revelation 20:17 And when the thousand years are expired, Satan shall be loosed out of his prison,
I'm sure you meant Revelation 19:7-8 but even then the Greek words used do NOT mean what you try to imply. The "righteous deeds of the saints" does NOT mean their deeds as the English could be understood. It means "a sentence of acquittal". It is God's forgiveness that clothed in white.
Once again the corrupted Catholic interpretation of scripture causes error.
