Jesus said to his disciples: "If your brother sins against you, go and tell him his fault between you and him alone. If he listens to you, you have won over your brother."
Gospel's Commentary
Today Jesus speaks to us about fraternity. No one should go through life on their own, least of all Christians. That is why we must help one another, even having the courage to gently correct someone who is mistaken and/or accepting correction ourselves.
—They say that “there is strength in unity.” Now imagine this as well: “Where two or three are gathered together in my name, there am I [Jesus] in the midst of them.” With Him on the “team,” we will obtain from His Father whatever we ask.
