"May your fountain be blessed, and may you rejoice in the wife of your youth." (Proverbs 5:18)
The father warns his son about the adulteress whose lips drip honey but whose end is bitter as gall, sharp as a double-edged sword. Her feet go down to death; her steps lead straight to the grave. Keep to a path far from her. Then the positive instruction: may your fountain be blessed, and may you rejoice in the wife of your youth. A loving doe, a graceful deer - may her breasts satisfy you always, may you ever be intoxicated with her love. Why be captivated by an adulteress? For your ways are in full view of the LORD, and he examines all your paths. The evil will be caught by his own cords of sin.
The Catechism identifies the conjugal covenant as the proper context for the gift of sexuality, where the mutual delight of husband and wife is not only permitted but celebrated as part of God's good creation (CCC 1611).
Brothers and sisters, the Bible's counsel on sexual fidelity is not merely prohibitive - it is positive. Rejoice in the wife of your youth. Be satisfied. Be intoxicated. The gift is given within the covenant for delight as well as for children. The adultery warning protects not a restriction but an abundance. Guard the gift by staying within it.
Lord God, bless the fountain of covenant love. Let married couples rejoice in each other and find in faithful love the abundance you designed it to carry. Through Christ our Lord. Amen.
