While the allegations are unproven, it's disheartening to say the least that someone would attempt to defend this with Scripture.  If you are looking for a reason for why less people are attending church, look no further than what modern Christianity has become: the very dictionary definition of "hypocrisy."

First you readily embraced (not grudgingly & transactionally accepted) Trump, a man who not only knows nothing about Scripture, but is a shining example of what a Christian man is NOT.  Now you are trying to defend potential statutory rape with God's book?!  What happened to absolute right and wrong?  

The validity of the accusations and trying to justify them with the Bible are two separate issues.   Stop using the Bible to defend the indefensible.
