The Gospel for this 25th Sunday of Ordinary Time warns us against resentment. Here is an extract from Pope Francis' 'The Joy of Love' which comments on the words of St Paul, that 'love is not resentful'.
'The Gospel tells us to look to the log in our own eye (cf. Mt 7:5). Christians cannot ignore the persistent admonition of God’s word not to nurture anger: “Do not be overcome by evil” (Rm 12:21). “Let us not grow weary in doing good” (Gal 6:9). It is one thing to sense a sudden surge of hostility and another to give into it, letting it take root in our hearts: “Be angry but do not sin; do not let the sun go down on your anger” (Eph 4:26). My advice is never to let the day end without making peace in the family. “And how am I going to make peace? By getting down on my knees? No! Just by a small gesture, a little something, and harmony within your family will be restored. Just a little caress, no words are necessary. But do not let the day end without making peace in your family”.112 Our first reaction when we are annoyed should be one of heartfelt blessing, asking God to bless, free and heal that person. “On the contrary bless, for to this you have been called, that you may obtain a blessing” (1 Pet 3:9). If we must fight evil, so be it; but we must always say “no” to violence in the home' (n. 104)
