Depends on the edition and array. In older editions, you only got a great benefit from your prim ability score.IME Clerics were generally pathetic at giving out damage, though they weren't bad at soaking it up.
As a Cleric, my one good stat is going into Wisdom; a second good stat goes into Dex or Con. Strength is way down the list.
In modern editions, you can get great benefit from moderately good scores and supplementing/boating with spells.
So it all depends on the calculation.
