Also, Christ’s vocation was to offer up His life in order to save us from our sins. If He married, He’d have had to leave poor Mary Magdalen, say, behind, feeling abandoned by Him, which might have eroded her faith in Him. It was rough enough on His Mother and she knew what He came here to do in the first place.
Plus, there’s something, I dunno, cringe-inducing about the idea of Jesus marrying. It takes away from His divine nature and while, yes, He was as human as the rest of us, we have to remember He was also God and there’s something a bit… creepy about God having a physical marital relationship with someone.
