Agreed. Unless the PD is also the Imam at a local mosque or the Cantor at your synagogue (or someone you regularly see at whatever house of worship you personally attend), you have no idea whether or not this person actually practices the faith. If you were interviewing for a Doctor of Divinity program instead of a job as a doctor, I'd say go for it. Otherwise, the potential downside far outweighs any minor potential upside.I might also ask how you know if the PD actually practices the religion which you share or feels fondly about it? Just because someone was raised in a certain faith does not mean that they are an active practitioner of it.
