Alexander spent four years in Syria, fighting the good fight, and his progress in the Lord was substantial. Although he adhered to every rule, he remained keenly attentive to whether monastic life were lived in accordance with holy scripture, and found that it was not. As devotees well know, the renunciation of wealth and care for the future enjoined in holy Gospel is not maintained in cenobitic life, where it is someone's job to provide for the brothers and attend to their needs. But Alexander was a slave of God, boiling over with the Spirit, and the words of the Master—"Take therefore no thought for the morrow" and "Ye are of more value than many sparrows"—were forever in his ears, and his inner turmoil could not be contained. [....]
With the Holy Gospel in his hand, he strode up to the abbot and asked, "The things that are written in the Holy Gospel, father—are they true?"
Now Father Elias was a father indeed, and the shepherd of an inference-making flock, and on hearing the blurted question he surmised that the Evil One had led this brother away from faith. Straightaway he fell with his face to the floor, and said nothing to Alexander but called to the others, "Come pray for this one, who struggles in the Devil's trap!" And for two full hours all the brothers wailed over him, begging God for aid.
The abbot then got to his feet and said, "How comes this question to you, brother?"
Alexander was undeterred. "Are the things in the Holy Gospel true, or are they not?" he asked.
"Yes," they all replied, "because they are the words of God."
"Then why do we not carry them out?"
"Because no one is able to." they said.
At this, Alexander's outrage was unrestrained. To be cheated into wasting all that time! He took his leave of the entire community and, clutching the Holy Gospel, set out to follow what is written there in imitation of our holy fathers. Hereupon, the prophet Elijah became his model, and he made his home in the desert, where he spent the next seven years heedless of earthly cares, living as the Holy Spirit dictated.
