It’s impossible to be a Christian and marry or even date well in a church that is sexually immoral and accepted as such due to innumerable factors, one of them being the threat of violent and seductive relational dynamics. It’s not safe socially or spiritually or physically, for the exultation of virginity in marriage which marriage by nature of itself exults, exposes all sexual immorality as deeply wrong in public, which is precisely what the church fears to do in the first place - cast out and judge the sexually immoral in public. Those who do not practice virginity before marriage or accept this rule must be rejected.
