By Casey Chalk, Crisis Magazine - For Catholics, there is no Church apart from the visible unity of the episcopal office, since this is the institution Christ established. Without the bishop, there can be no Eucharist, the very heart of Catholic life. To depart from these would be to form or join a schism from the Church Christ founded. And there is simply no sin by members of the Church that justifies the additional sin of schism. Indeed, we should rather be more willing to die than to commit any sin, including the sin of schism.
