Christian marriages are not exempt from the possibility of unfaithfulness, and as we know, even Clergy marriages break down. The growing apart syndrome can be the start of this. Lack of devotions together can be another factor. The general atmosphere of permissiveness is regularly pumped into our homes via the media, and it can subtly erode our standards. Adultery is often the theme of contemporary books and films. It may be referred to as an affair, or by the high‑sounding phrase of "extra‑marital relationships". But whatever designation is used, God calls it sin and it breaks the seventh Commandment. In the Old Testament it was a capital offence, although, mercifully, it was rarely carried out.
Christian marriages must be examples to the younger generation, and in missionary situations, the behaviour of the Christian family is as powerful as the preaching.
We must never forget that the strength of a nation and the Church is largely determined by the strength of its homes and families.
