If water has spiritually efficacy, how many other physical things have spiritual efficacy?   

The whole concept of rituals having spiritual efficacy is pagan in its origins.

Where is ritual in this offer from Him?   

Come out of the dregs of Catholicism and be a Spirit Filled, Grace Through Faith, New Creature who is a Son Of God with the Mind Of Christ operating in His authority and power.
