There were four country churches in a small town: one Presbyterian, one Baptist, one Methodist, and one Catholic. One day, the four churches were infested by squirrels.
The Presbyterian church convened a meeting to decide what to do with the squirrels. After much prayer and consideration, the Assembly determined that the squirrels were predestined to be there and that they should not interfere with God's will.
In the Baptist church the squirrels had taken refuge in the baptismal font. The elders got together and decided to put a lid on the font and drown the squirrels there. Somehow, the squirrels escaped and the following week they had doubled their number.
In the Methodist church, the faithful came together and decided that they were not in a position to harm any creature of God. So they carefully caught all the squirrels and set them free a few kilometers outside of the town. Three days later, the squirrels had returned.
The Catholic church had the best and most effective solution. They baptized the squirrels and registered them as members of the church. Now the squirrels only show on Christmas and on Easter Sunday.
