Never received a reply, and it's been a year now.  If I remember correctly, the client in question could have been insured under his wife's policy, but chose not to, so he was not allowed the deduction based on this.  If your clergy client has only this one health insurance policy, I would include it with clergy business expenses on the Sch SE, as long as it does not surpass his clergy self-employment income and he/she does not have other types of self-employment income to which it would need to be allocated.
