Based on Mark 10, all divorce and remarriage is a sin.
“...all divorce and remarriage is a sin.”
Matt 19:
“Whosoever shall put away his wife, except it be for fornication,...”
Not exactly. It’s important that you look at the time, and the kinds of things Jesus was denouncing. Unless someone was being an unrepentant in adultery, this was understood, but some religious leaders at the time were getting divorced and remarried to younger women, for pretty frivolous reasons. Sorry, but if one isn’t doing divorce for the fact that someone is being stubbornly unrepentant about adultery, or there is a serious need to leave the spouse for abusing you and/or the children, divorce is wrong. Divorce, should be a last resort to marital problems, not a casual solution for a general fact that you don’t spontaneously live happily ever after.
