The division was caused by a number of factors: differences of opinion about the priority of apostles and prophets; different views of grace and law, women in ministry, and relating to contemporary culture; and a discussion about appropriate discipline for an early leader. It was finally catalysed by a letter setting out the problems sent by Arthur Wallis to the other early leaders. A number of attempts to repair this breach were made, and within a few years there was some dialogue again. However, the shared vision of earlier times was never regained.
