The standard is absolute: no sexual relationship before marriage, complete fidelity within it, and no divorce except in extremity. Members describe it as the discipline that makes the rest coherent, given that the fall is read as a sexual failure. Two things sit awkwardly beside it in the record. The founder's own biography — an early marriage that ended, and children outside the blessing — was published by his former daughter-in-law and has been contested by the church. And the second generation, raised inside the standard and living in societies that do not share it, is where the argument now runs.
