Marriage is for life, and only ends, according to the law, when either husband or wife dies. It belongs to this world, and does not continue in the world to come.
When we read these rules, we see that marriage is serious and binding. It should cause us to tremble that we might make one of the most serious decisions we make when we are still immature. Be careful; pray. Don’t get into form of behaviour that will accelerate marriage before due consideration has been given.
How long should courtship be? As a guidance if a person is under 22, courtship should last at least a year before they marry. The only exception is when there is a lot of pain in the waiting. Courtship should probably not be less than 6 months.
If the pastor feels that a couple are not compatible, should he refuse to marry them? Yes, initially he might do so, but if they are persistent, then the opposite could be worse: they leave the church and marry anyway.
If a pastor marries a believer to an unbeliever, doesn’t he undermine his preaching? To marry in the Lord is their Christian duty, but you cannot throw them out of the church. You do your best to warn them. They are fond of each other, and he respects her faith, let us say. It is better to marry them rather let them leave and he senses the cruelty of the church. You come to the point where you do marry them. Does that set a precedent? Yes, it does, but in other areas we do this. We accept a gradation in conduct. Undoubtedly you should marry only in the Lord, but it is not an excommunicable offence.
