A not-so-hypothetical question: you have snow birds who have been attending your congregation for a couple of years. They've resisted membership because they maintain membership in their "southern" church. Now they are wondering if they can become dual members (like dual citizenship?) at both churches. Their hearts are in the right place - they want to have committed relationships with the congregation that they are in. They know that membership does not provide them with much in terms of benefits, since we will care for them regardless. They simply want to formalize the relationship. So, what do you do?
