Actually the Bible does have some things to say about adultery and divorce. You do have an concordance don’t you? As far as contraception, the command was to go out and populate the earth. I think Onan was struck down for disobedience. But now at this time we are at 7 Billion people. I believe we have fulfilled that command (and the earth) and it’s time to put the brakes on.
And where is that spelled out in scripture? Where does God set a limit on the number of souls permitted to inhabit the earth that He created? Or, is this Your Own Personal Interpretation Of Scripture? Is this "teaching" standardized among ALL non-catholic churches?
I disagree, but accepting for the sake of argument that you are correct, does that warrant the complete acceptance of abortifacients and hormonal birth control methods that prevent the embedding of a fertilized embryo accepted by all Protestant denominations today?
Peace be with you
