Marriage and Procreation

Description
The divine blessing "Increase and multiply" as God's approval and blessing of marriage, not a precept binding every individual, and the creation of man and woman for complementary union

The divine blessing "Increase and multiply" as God's approval and blessing of marriage, not a precept binding every individual. If there is any precept, it is given not to individual persons but to the whole species, lest the human species die out -- otherwise Christ would be the first violator. "Male and female He created them" -- not a hermaphrodite, but Adam as male and Eve as female.
