“Let us then guard our hearts, let us guard our mouths. Both have been written about. In this place we are bidden to take heed to our mouth; in another place you are told: “Keep your heart with all diligence” (Proverbs 4:23).
If David took heed, will you not take heed? If Isaiah had unclean lips — who said: “Woe is me, for I am undone, for I am a man, and have unclean lips” (Isaiah 6:5) — if a prophet of the Lord had unclean lips, how shall we have them clean?
But for whom was it written, unless it was for each one of us: “Hedge your possession about with thorns, and bind up your silver and gold, and make a door and a bar for your mouth, and a yoke and a balance for words” (Sirach 28:24-25)?
Prior to going back to Egypt to liberate the children of Israel from captivity, the Prophet Moses had an encounter with God on Mount Horeb. Seeing the glory of God being manifested through a burning bush, he fell to his face in fear of looking at God, as God had revealed to him: “I am the God of thy father, the God of Abraham, the God of Isacc, and the God of Jacob” (Exodus 3:6). God revealed to him that He was, out of His love and compassion, displeased of Israel’s bondage to captivity, and that He would deliver them and bring them to a land which is good, large, and flowing with milk and honey (Ex 3:7-9). After God had told Moses that He would send him before Pharaoh to deliver the nation of Israel, he had doubts pertaining to his capability; and also questioned how he should identify God when the Israelites were to ask of His Name. In response, the Lord told the Prophet: “I AM THAT I AM … thus you should tell the children of Israel; ‘I AM has sent me unto you’” (Ex 3:14).
This Holy Name given by God, which was revealed to Moses by His Word, emphasizes that “God is the supreme existence, and is therefore unchangeable, the thing that He made He empowered to be, but not to be supremely like Himself” (Augustine of Hippo, The City of God, Book 12, chap. 2). Because of this sacred truth, St. Moses tells us that it was “In the beginning, God created the Heavens, and the Earth” (Genesis 1:1), as He is ever eternal, infinite, without beginning, without end, and the Creator of all things and the source of their very existence out of nothing – all by the Self-Same Word (Genesis 1:3-31). St. Augustine tells us that when God created all things, “He communicated a more ample, to others a more limited existence, and thus arranged the natures by ranks” (The City of God, Book 12, chap. 2). In other words, when God created all things, He established a hierarchy; with man being the highest of all the carnal creatures, “For man is more honorable than any created thing…” (John Chrysostom. Homily 56 on the Gospel of John).
This is what Abba Daniel, the Pharanite, said, ‘Our Father Abba Arsenius told us of an inhabitant of Scetis, of notable life and of simple faith; through his naivete he was deceived and said, “The bread which we receive is not really the body of Christ, but a symbol.”
Two old men having learnt that he had uttered this saying, knowing that he was outstanding in his way of life, knew that he had not spoken through malice, but through simplicity. So they came to find him and said, “Father, we have heard a proposition contrary to the faith on the part of someone who says that the bread which we receive is not really the body of Christ, but a symbol.”
The old man said, “It is I who have said that.” Then the old men exhorted him saying, “Do not hold this position, Father, but hold one in conformity with that which the catholic Church has given us. We believe, for our part, that the bread itself is the body of Christ and that the cup itself is his blood and this in all truth and not a symbol. But as in the beginning, God formed man in his image, taking the dust of the earth, without anyone being able to say that it is not the image of God, even though it is not seen to be so; thus it is with the bread of which he said that it is his body; and so we believe that it is really the body of Christ.”
