Because it's weak when compared with equal levels of intelligence with other catalyst like the Sorcerer's Catalyst, and you still must have the minimum intelligence require to cast the spell. These two factors mean you'd need to be maintaining relatively equal levels of both faith and intelligence, which costs a lot of points. Even then, you'd be better off using a normal catalyst because, as I said, you'll get a better magic adjust. Just like Velka's Talisman, making a hybrid caster doesn't work when it's not actually profitable to do it.

Unless you're just using Magic Weapon on a faith build or something, I can't see any practical reason to use this.
