Belonging to one of these communities enables members to intentionally focus on their Christian life, through bible study, prayer, and service to others, with the support of other caring Christians. For over twenty-five years, the members of St. Martin's have held a giant Garage Sale on the first weekend in June. People come from as far as Illinois to attend the sale. Proceeds support the Church and many outreach projects. The Sale also provides members an opportunity to get to know each other better as they work together.
Parishioners donate and collect clothing and household items throughout the year.
During May, members travel all over West County picking up washing machines, couches, chairs, televisions, baby furniture and other items too heavy or too big to bring to the church in a car. ECW Women of St. Martin's - The Women of St. Martin's is an organization open to all women. The purpose is fellowship and service. Men of St. Martin's - The men of St. Martin's meet socially on Friday evenings during the spring, summer, and early fall to play golf and relax among their fellow parishioners. During the annual Garage Sale in June, the men operate a BBQ stand selling refreshments to raise funds for the church.
