That applies to spiritual marriage, not homosexuality.. Specifically Twin Flames, and not everyone is one... so the rest of humanity is just fucked, by not able to fuck as they choose? This is the kind of crap Lucifer had a problem with, and on this stuff he was right.
No, that doesn't apply to spiritual marriage. In the entire chapter 19 of Matthew, Jesus is speaking of physical, earthly marriage and divorce. In addition, did you miss the word "flesh" in verses 5 and 6 below? Here, I'll post it again.
“Have you not read that He who made them at the beginning ‘made them male and female,’ and said, ‘For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one
flesh’? So then, they are no longer two but one
flesh. Therefore what God has joined together, let not man separate.”
Matthew 19:4-6
