John Chrysostom

See the wisdom of the Teacher. Being asked, Is it lawful, He said not straight, It is not lawful, lest they should be troubled, but establishes it through a proof. For God made them from the beginning male and female, and not merely joined them together, but bade them quit father and mother; and not bade the husband merely approach his wife, but be joined to her, shewing by this manner of speaking the inseparable bond. He even added a still closer union, saying, And they twain shall be one flesh.
