Last week, we had the joy of celebrating the Baptism of Alfonso Williams at Old St. Mary's.
Celebrated by Fr. John Maksym, this beautiful sacrament marks the beginning of a lifelong journey of faith in Christ. We give thanks for this special day and pray that Alfonso continues to grow in God's love and grace throughout his life.
Please join us in congratulating Alfonso and the Williams family. Welcome to the Church! ✝️
