We do not have to like someone's actions, but liking and loving are two very distinct realities. You can love a person, but you don't have to like the way he or she behaves. Ask any mother of a badly behaved child what it means to love the child and not like his or her behaviour. We can bless the sinner, but we must not bless the sin. We can bless two people who need our love and mercy, but we must not bless the adulterous union into which the two people have entered. In other words, relying on the grace of God, we can be like Jesus Christ by generously welcoming the sinner but calling the sinner to an intimate communion with Jesus and His Church. Christ welcomed sinners but called sinners out of sin into authentic freedom and love (St. John 8:11).
And the (prodigal) son said (confessed) to him, ‘Father, I have sinned against heaven and before you (the son acknowledged his sins); I am no longer worthy to be called your son (the son is humbled, penitent, sorry for his sins).’ But the father said to his servants, ‘Bring quickly the best robe, and put it on him; and put a ring on his hand, and shoes on his feet; and bring the fatted calf and kill it, and let us eat and make merry; for this my son was dead, and is alive again; he was lost, and is found (the father restores the penitent child to life).’ And they began to make merry.—St. Luke 15:21-24
(God o)ur Father is moved to compassion whenever we repent, and (H)e sends us home with hearts calm and at peace. He tells us that all is remitted and forgiven. God’s forgiveness knows no limits; it is greater than anything we can imagine and it comes to all who know in their hearts that they have done wrong and desire to return to (H)im. God looks at the heart that seeks forgiveness.
