There is an opportunity for personal confession after Mass each day. And from 11—12 on Saturday. Confessions is a great occasion to receive the Mercy and forgiveness of God our Father in the Sacrament he has given us. It is a great time of joy and peace which he wants us to treasure and celebrate. There is no Communal Penitential Service.
