As academic biblical scholars, we wish to clarify that the biblical texts do not support the frequent claim that marriage between one man and one woman is the only type of marriage deemed acceptable by the Bible’s authors.
Monogamy is the Church’s teaching, drawn from Scripture.
This goes back to the game the other day… Does Scripture ever explicitly state marriage is to be between one man and one woman? No.
We’d rather have to define marriage first and then decide if it is something we in the modern world can live with, politically speaking.
As for me, I’d rather a Two-Kingdoms approach here, but that’s Luther and Luther is nearly always wrong.
