more wisdom contained in the Bible:<quoted text>
Having children is natural. Sterile sex is unnatural. All (normal) mammals seek to reproduce.
Men and women have different qualities and different strengths and weaknesses. One of the purposes of marriage and one of the reasons that the Church considers it a sacrament is that God is uniting the complementary attributes and skills of one man and one woman together to become a complete unit under God.
Two men and two women don't compliment each other in the same way that a man and a woman can.
This seems to be lost on the pop culture people who have been brainwashed to believe that the Bible is a series of superstitions and myths without realizing the wisdom it contains.
