Many Independent Catholic communities are small, are led by an unpaid clergy, and lack a stable schedule or location. Larger Independent Catholic communities have often resulted from schism within the Roman Catholic Church or are often led by clergy who were formed by and formerly ministered to the Roman church; these communities often resemble mainstream churches with a larger population of laity and a small number of paid clergy. In Independent Catholicism, freelance ministries meeting the needs of a small number of persons are far more common than large parishes.
