Once a month, usually on the first Sunday of the month, there is a contemporary worship service held at St. Gregory's Church. The Simple Gifts Eucharist is conducted in Harris Hall concurrently with the 10 a.m. service in the main church. It offers an interesting contrast to the formal worship experience. The Simple Gifts setting is informal, with chairs arranged in a semi-circle, and an altar covering made of fabric covered with the hand prints of children.

The music is supplied by acoustic guitars and often, a visiting bass fiddle. The "hymns" consist of old favorites, modern praise music and some original compositions. The liturgy and song lyrics are simple and joyful and are projected on a screen for all to see.

Following the Gospel and a short homily, the children (and any grownups who are interested) are invited to participate in a craft activity designed to integrate with the themes of the service. Communion is receieved standing up, in a large circle around the room. While attendance varies, the service has sometimes attracted as many as a hundred worshippers of various ages. It is not a child's service, per se, but a service shaped to be enjoyed by the young-at-heart.
