Sunday worship at St. Matthias centres on two services, both taken from the Anglican "Book of Alternative Services", with a celebratory service at the main, 10:30 a.m. service (usually p. 185), and a traditional one at the 8 a.m. service (usually p. 230). There is also a 10 a.m. service on Thursdays in the chapel.
Music with choir and organ is an important feature of the main service, which is followed by coffee and fellowship in the church hall. Worship is also enhanced by the beauty and serenity of the surroundings, with the large stone church on the brow of a hill surrounded by gardens tended by parishioners and, inside, graced by magnificent stained-glass windows and the work of both the Altar Guild and the Ecclesiastical Arts Guild.
Many dedicated parishioners offer their services as sidespersons, intercessors and readers at the two Sunday services. As well, many do double duty in other church capacities (for example, as choir members and servers). New people are welcomed.
