I don't really understand how the multiverse theory goes against God. I mean, God never said that it was true but at the same time, I don't see how it goes against God. If the multiverse theory is true then you should be able to pray to God to take you to a parallel universe where certain conditions are true. At the simplest level, you could flip a coin, place the coin in a jar and pray to God that you enter a universe where the coin had landed on the opposite side but yeah, you should be able to go down alternate branches from a past point in what you perceive as a linear flow of time. I myself vividly remember as a child, praying to God for Tomb Raider 2 and waking up in the morning with the disc lying on the middle of my floor (unfortunately, I didn't pray for a memory card). It might be possible to pray to God to work as a pastor in some kind of alternate fantasy Universe. I like the idea of being a Christian Magical Girl personally. If it was by God's will, I'd definitely become one. I think my preferred power would be sand-manipulation like Crocodile from One Piece or Gaara from Naruto. I'd love to Christianise the masses in such a world and defeat blasphemous, heinous Magical Girls in the name of God.
How does the multiverse theory even comment on anything regarding the Universe's origins?
Also, I've frequently come upon the notion that Christ is a 5th dimensional being. Is that blasphemous?
