Seminary Graduation Gift Ideas

Gift card to appropriate book store (Lifeway for example).

how about going to a Christian bookstore and getting a gift certificate. he probably has many books but in time he might find he needs more.
maybe a dinner out. being in school he has probably been pretty poor.

If there are local artists in the town in which he is
graduating, perhaps there are renditions of the
seminary, or of the chapel or church he has
attended there.

there will probably be some traveling in their future, how about luggage, an onboard carryall, a basket with travel goods in it...
