A Note from Father Vagenas

Welcome!

Wherever you are on your faith journey, you are in the right place.

OCIA is a wonderful opportunity to discover the beauty of the Catholic faith and prepare to receive the Sacraments of Baptism, Confirmation, and the Eucharist.

Jesus longs to have a personal relationship with each one of us, and that relationship begins by coming to know Him more deeply. Long before we ever begin searching for Him, He has already been searching for us.

I would be honored to accompany you on this journey of discovering who Jesus is and the incredible life He desires for you. Even if you are not yet sure whether you are ready to become Catholic or complete your sacramental initiation, please don’t hesitate to reach out. I’d be happy to answer your questions or simply have a conversation with you.

I hope to meet you soon.

God bless,
Fr. Vagenas
Parochial Vicar
