To His Father, When He Had Entrusted to Him the Care of the Church of Nazianzus.
1. I opened my mouth, and drew in the Spirit, and I give myself and my all to the Spirit, my action and speech, my inaction and silence, only let Him hold me and guide me, and move both hand and mind and tongue whither it is right, and He wills: and restrain them as it is right and expedient. I am an instrument of God, a rational instrument, an instrument tuned and struck by that skilful artist, the Spirit. Yesterday His work in me was silence. I mused on abstinence from speech. Does He strike upon my mind today? My speech shall be heard, and I will muse on utterance. I am neither so talkative, as to desire to speak, when He is bent on silence; nor so reserved and ignorant as to set a watch before my lips when it is the time to speak: but I open and close my door at the will of that Mind and Word and Spirit, Who is One kindred Deity.
