There is no other name by which we must be saved. That we may be able always to pay attention to Christ, and be zealous in this at all times, let us call on him who is the subject of our thoughts at every moment. And of course those who call upon him need no special preparation or special place for prayer, nor a loud voice. For he is present everywhere, and is always with us; he is even nearer to those who seek him than their very heart. It is fitting, then, that we should firmly believe that our prayers will be answered.
–Saint Nicholas Cabasilas (c. 1321–1392)
