Any adult who is sexually attracted to a child has severe emotional problems and to justify such desires using history and Mary, the mother of Jesus is ludicrous. Let me ask you this question, have you studied the long-term adverse consequences of using children as sexual objects? Is your love for children so selfish that you can ignore the life-long trauma that many children carry into their adult lives after sexual encounters with adults as children?
If you love is “pure” and “unselfish” you will put the welfare of the child ahead of your baser animalistic sexual drives. Jesus told His disciples:
Mark 10:14-16
14 But when Jesus saw this, He was indignant and said to them, "Permit the children to come to Me; do not hinder them; for the kingdom of God belongs to such as these. 15 "Truly I say to you, whoever does not receive the kingdom of God like a child shall not enter it at all." 16 And He took them in His arms and began blessing them, laying His hands upon them. NAS
Matthew 18:5-6
5 "And whoever receives one such child in My name receives Me; 6 but whoever causes one of these little ones who believe in Me to stumble, it is better for him that a heavy millstone be hung around his neck, and that he be drowned in the depth of the sea. NAS
Your example of Mary, the mother of Jesus, is as ludicrous and heretical as those who teach Christ was gay.
Galatians 6:7-8
7 Do not be deceived, God is not mocked; for whatever a man sows, this he will also reap. 8 For the one who sows to his own flesh shall from the flesh reap corruption, but the one who sows to the Spirit shall from the Spirit reap eternal life. NAS
If you continue to sow to the baser aspects of the flesh you will reap the consequences.
