The Sunday service at any Trinity Church brings together people from all walks of life. The service typically begins with a choir performance, followed by readings from the Bible and a sermon from the minister. The message is often centred around the teachings of Jesus Christ and how they can be applied to daily life.

The congregation participates in prayers and hymns, and there is usually an offering and communion is four times a year. The Sunday service provides a sense of community and a space for reflection and contemplation. It is a time to connect with God and with others who share similar beliefs and values.
