NOTES for Mat 19:1-15
Indeed, not everyone can accept this saying. If this is the "duty of a man toward his wife," if now you cannot exist on your own, but have become one flesh (that is, one body, one human being) with someone else, and if you are completely unprepared for such a step, then it is better not to marry. After all, the Pharisees, as always expressing the common human point of view, ask Jesus: is there no way to combine pleasure with usefulness? Is it not possible to be one flesh for a while, until it becomes very hard and painful, and then step back?
Almost every moral dilemma of modern humanity falls into this category of questions: how can we make things good without making them difficult? In response, Christ exposes them not for cowardice, not for irresponsibility, not for selfishness, but for hardness of heart, for the inability to see the beauty of God's design for the unity of man and woman, for the inability to love truly and deeply. It appears that all our problems connected with marriage and family arise precisely from hardness of heart, from the deadening of the organ of love.
