April 25th is the Feast of St Mark the Evangelist.
Mark journeyed to the city of Alexandria; and when he entered in at the gate, the strap of his shoe broke.
And when he saw this, he thought: «Now I know that the Lord has made my way easy».
Then he turned, and saw a cobbler there, and went to him and gave him the shoe that he might mend it.
And when the cobbler received it, and took the awl to work upon it, the awl pierced his hand. So he said: «Heis ho Theos»; the interpretation of which is, «God is One».
And. when the holy Mark heard him mention the name of God, he rejoiced greatly, and turned his face to the East and said: «O my Lord Jesus, it is thou that makest my road easy in every place».
Then he spat on the ground and took from it clay, and put it on the place where the awl had pierced the cobbler’s hand, saying:
«In the name of the Father and the Son and the Holy Ghost, the One living and eternal God, may the hand of this man be healed at this moment, that thy holy name may be glorified».
Then his hand at once became whole.
[…] The cobbler remained astonished at the power of God which descended upon the holy Mark, and said to him: «I pray thee, O man of God, to come to the dwelling of thy servant, to rest and eat bread, for I find that to-day thou hast conferred a benefit upon me».
[…] After they had eaten, the cobbler said to him: «O my father, I beg thee to make known to me who thou art that hast worked this great miracle».
Then the saint answered him: «I serve Jesus Christ, the Son of the ever living God». The cobbler exclaimed: «I would that I could see him».
The holy Mark said to him: «I will cause thee to behold him». Then he began to teach him the gospel of good tidings, and the doctrine of the glory and power and dominion which belong to God from the beginning, and…ended by saying to him:
«The Lord Christ in the last times became incarnate of the Virgin Mary, and came into the world, and saved us from our sins». And he explained to him what the prophets prophesied of him, passage by passage.
[…] Then when the cobbler had heard wisdom and the words of the Scriptures from the holy Mark, together with the great miracle which he had seen him work upon his hand, his heart inclined towards him, and he believed in the Lord, and was baptized, he and all the people of his house, and all his neighbours.
