Holy Trinity Sunday School


Holy Trinity is fortunate to have a very strong and thriving Sunday School program. The Sunday School program teaches our children and youth the Orthodox faith through teachings of the Bible as well as materials obtained from the Greek Orthodox Archdiocese.

Our Sunday School serves children from age three to seniors in High School. Our school year runs from September to May each year. Sunday School begins immediately following Holy Communion and lasts for about a thirty-minute period once class begins. Our Sunday School students put on the annual Christmas Program. 


For more information, please contact or call the Parish Office.

Complete our registration form to register your children and return it to the Sunday School Director.

Resources for Kids

Daily Orthodox Scriptures for Kids Starting with the Gospel according to Matthew, we will read through the New Testament.  All our readings are by kids. There is a short commentary at the end just for kids (though Fr. Alexis certainly doesn’t mind if others listen). Usually around five minutes long, it is a fantastic way to get our children into the Bible. Join us on the journey through the New Testament!
