For the love of money is a root of all kinds of evil. Some people, eager for money, have wandered from the faith and pierced themselves with many griefs.
-I Timothy 6:10, NIV
Divorce is not sin.
It is like transferring money from one account to another. The act itself is not a sin.
However, the context might change whether or not that act is sin.
If you are transferring money illegally from someone’s account without their knowledge, that is called theft. It is a sin.
Similarly, if you are divorcing a spouse to discard them in order to just marry and sleep with a more attractive (to you) alternative, that is adultery. It is a sin.
Just because someone transferred funds does not necessarily tell you whether or not this person sinned by such a transfer.
Similarly, just because one is divorced does not necessarily tell you whether or not this person sinned by getting divorced.
I wish more Christians understood this basic biblical perspective on divorce. It would alleviate considerable suffering for divorced Christians who are unjustly shamed for their godly divorce.
