Sunday School

The goal of our Sunday School program is to mold the lives of our children in the Orthodox Christian ethos. We will utilize the teachings of Holy Scripture and Holy Tradition to develop each student spiritually, and guide them towards living a Christ-centered life. Our hope is that by having our children actively participating in the liturgical, sacramental, and communal life of the Orthodox Church, they will develop a personal and lifelong relationship with our Lord and Savior.

Our director and teachers are fellow parishioners who love children and show a desire to serve our Lord through the stewardship of teaching.

The curriculum in use is from the Greek Orthodox Archdiocese Department of Religious Education and is supplemented with other materials and activities obtained from other Orthodox Christian sources. Our program is closely moderated by our devoted youth priest, Father Christos Kalaitzis.

We are looking forward to a fun and fulfilling year ahead guiding the children as they use their heart, their art, and their songs to glorify Him and sing His praises! Don’t forget to register!
