Our Catholic faith teaches us that marriage is a Sacrament, meaning that there is actual grace in a Sacramental marriage. This grace is what assists husbands and wives to live out marriage joyfully, sacrificially, and lovingly. However, we are still Fallen creatures so even with the grace present in a Sacramental marriage we suffer from concupiscence, the propensity towards selfishness and sin, which causes us to wound each other.
In the gospel’s account of the Baptism of the Lord, we hear the Father’s voice, “This is My beloved Son, in whom I delight.” And when we look at Jesus, of course, what’s not to delight in? He’s a chip off the old block in a way that no other son ever has been or ever will be. What could His Father say but, “That’s My boy”?
