Chapter on the Cross with One Finger
Regarding the [Sign of] the Cross with one finger: It has been mentioned in the Torah that God the Exalted commanded His servant and prophet Moses to sprinkle with his finger the blood of the sacrifices—which the people offered as an oblation—upon the Tabernacle (the Tent of Meeting), the vessels of service, and the people for their purification. He did not say to sprinkle it with his fingers.
Furthermore, our Lord—to Him be the glory—said when addressing the Jews, as witnessed by the Gospel of Saint Luke: "But if I cast out demons by the finger of God, then the kingdom of God has come upon you." He did not say "by the two fingers of God." This [the single finger] points to the Oneness of the Creator’s Essence, the Trinity of His Persons (Hypostases), and the One Nature that came to be by Union—contrary to the opinion of those who claim two natures.
Our starting [the motion] from the left to the right signifies that, through our reliance on the Holy and Unified Trinity, we have transitioned from the "party of the left" to the "party of the right." This was similarly mentioned by Saint Cyril I, the twenty-fourth Patriarch of the See of Alexandria and the Teacher of the Church, when he said in his Liturgy: "From the rising of the sun to its setting, and from the North to the Right [South]." He did not say from the right to the left.
In summary: the Copts of Egypt, the people of the Five Cities (Pentapolis), the Nubians, and the Abyssinians (Ethiopians)—ever since they were discipled by Mark the Apostle and accepted the faith in the Lord Christ and His life-giving Cross—have never signed the cross or blessed themselves except with one finger. We follow this custom, and upon this principle, we continue.
