Nicene Fathers such as Augustine believed that marriage was a sacrament because it was a symbol used by Paul to express Christ's love of the Church. However, there was also an apocalyptic dimension in his teaching, and he was clear that if everybody stopped marrying and having children that would be an admirable thing; it would mean that the Kingdom of God would return all the sooner and the world would come to an end. Such a view reflects the Manichaean past of Augustine.
