It says in the players handbook that you get to add any deflection bonus to a characters touch AC.

The cleric spell shield of faith says it provides the recipient with a deflection bonus... there's no question there that this adds to the characters touch ac.

My question is whether or not the regular shield spell works the same way. It doesn't specifically say that it grants a deflection bonus but logic makes me want to think that it does even without saying as much. 

If the spell shield does in fact add to a characters touch AC, then does Mage armor also work this way?

I could see this question being argued both ways and really wish the spells descriptions were more specific on this note. I mean the shield of faith spell covers the deflection topic, why not include the yea or nay into the other descriptions for similar spells.
