This question was recently presented to me and it is a good question. Should we give the pastor who baptizes our children an honorarium? After all, we do so when a pastor performs a wedding, and sometimes even a funeral. Where should we draw the line?
For baptism, the answer is clearly in the “no” category. Performing baptisms, like administering the LORD’s supper and preaching, are a part of a pastor’s regular duties. The pastor is charged with administering the normal means of grace, of which are baptism and the LORD’s supper. It would be quite odd for a pastor to expect additional money for doing what he was hired to do.
Performing weddings is a different story since he is under no obligation to conduct the ceremony. He does so for the blessing of the couple involved and gives up personal time on a Saturday, therefore he should be compensated for doing so.
