It was considered sinful to remarry unless you were divorced due to adultery.
Besides, the CC didn’t institute celibacy as rule for priests until hundreds of years later after Christ’s death. That tells me the rule of celibacy was man made and instituted rather than Biblical.
I’d argue that abuse is grounds for divorce.

Your injection of the history of celibacy in the Church is completely irrelevant to the interpretation I've presented!
