The handsome church at Concepción looks essentially as it did more than 200 years ago when it stood at the center of local religious activity. From the beginning, Mission Concepción hosted religious festivals. The friars strove to replace traditional Native American rituals through the demonstration of Christian ideals. Morality plays, such as Los Pastores, a colorful drama honoring the birth of Christ, were common in practice. In addition, the friars formalized the natives' acceptance of Catholicism through the adminstration of the sacraments. Many Native Americans continued to practice the Catholic faith after secularization.
