Well, sadly, an L2 priest can't cast Sermon of Courage. Putting artillery items on them is an option, as Arryn pointed out, but the priests generally have crumby aim; only items with 100 accuracy or area of effect spells are particularly useful on them.

Incinerate, from the Rod of the Phoenix, never misses and generally kills (or at least seriously damages) what it hits.

Of course, if equipping your L2 priests is too much of a bother and you absolutely refuse to pay their measly 1.67gp/turn upkeep cost, you can always suicide them since they're commanders and can go off into hostile territory by themselves.
