Our Lady of Sorrows loses her feast because of the Sunday Liturgy having preference. I am sure she does not mind and the Gospel must also be one of her favorite Gospels as Jesus tells us three parables of love and mercy. (Luke 15:1-32, shorter form is 1-10).
It begins with the tax collectors and sinners drawing near to listen to Jesus. The Pharisees and scribes began to complain, saying, "This man welcomes sinners and eats with them." So Jesus tells them this parable: "What man among you having a hundred sheep and losing one of them would not leave the ninety-nine in the desert and go after the lost one until he finds it? And when he does find it, he sets it on his shoulders with great joy and, upon his arrival home, he calls together his friends and neighbors and says to them, 'Rejoice with me because I have found my lost sheep.'
