Whether or not churning cap only sacreds every turn rain or shine is worth it depends very much on their nature, and your bless.
If they're really kick-butt and your bless will let them be effective all the way to the endgame (like Living Pillars or Palashankas), then yeah, I'd churn them day in, day out (gold providing).

If it's something like an Eagle Warrior or Ulm's Steel Warriors, probably not as they'll be either made obsolete by summons or impractical to leverage down the road. They're a boon for early expansion but after that, meh. I'd rather that gold went into castles, mages and labs than going into the recruitment and upkeep of stuff that won't help me reliably.
