Pastors and Priests Boycott Performing Weddings?

“Now tell us what you think about this: Is it right to pay taxes to Caesar or not?” But Jesus knew their evil motives. “You hypocrites!” he said. “Why are you trying to trap me? Here, show me the coin used for the tax.” When they handed him a Roman coin, he asked, “Whose picture and title are stamped on it?” “Caesar’s,” they replied. “Well, then,” he said, “give to Caesar what belongs to Caesar, and give to God what belongs to God.””
Matthew 22:17-21 NLT

This verse clearly speaks specifically about paying taxes. However in a broader sense, Jesus seems to suggest an appropriate separation of church and state. He suggests for us to give appropriately to both the church and state. 

I have heard many Christians concerned that the legalization of gay marriage will require pastors to go against their sincerely held beliefs and marry homosexual couples. I have no crystal ball or prophetic word to answer that question, but for now I will believe that possibility as real. So though I have no answer for that question, I do have a thought about a possible solution 

Many countries have separate civil and church marriages. Things here get a little confusing because the pastor or priest is acting as an agent of the State and God simultaneously. If we segregated those two roles, it would be much harder for the state to require a pastor or priest to go against his sincerely held beliefs. 

This could happen two ways. Pastors could just stop signing any marriage certificates. The happy couple would have to get their civil marriage at the courthouse and their church wedding with their pastor or priest. 

Alternatively, we could have state legislature that would separate the civil and church weddings. State legislature would be more difficult but the wall of separation would be stronger. Probably the best strategy would be to implement the first strategy while working on the second. 

This idea could push off the conflict regarding pastors being forced to perform weddings indefinitely. Many pastors might feel slighted, but there would be a great deal of freedom gained by releasing these rights.
