Though it's not at all what it is depicting, I have had many people say this icon looks like St. Moses is about to throw a punch.
I think it is a matter of great worth and a blessing to note what Abba Moses was doing on this icon for the sake of those who might not know the story and for those of us who would benefit from being reminded of it, while reading this thread. Here is the paraphrased version of the story.
Among his brothers the monks , one brother was found committing a personal sin. the Abbott of the monastery called Abba Moses to come and judge this brother’s action. Abba Moses, came in obedience to the Abbot’s summon, however he came to the meeting carrying a basket full of sand with a hole in it, so that the sand trailed behind him from that hole. The brothers asked what Abba Moses was doing; his reply was one of bravely imitating Christ, in the face of such brothers who were incited by the Evil One to become a gang of moral police who in the name of good were demanding the condemnation of their brother for his personal sin. his reply was that of sincere humility of someone who has never forgotten of what kind of chain he was set free from, of what kind of Forgiveness he has received from Our Lord and Savior Jesus Christ Crucified and Resurrected; it was a reply of one who in matters of personal sin choses only to look at and judge the state of his own heart, and not another’s who is also a sojourner in this world, let alone one who is engaged in the good fight.
So what was his reply? He said ‘my heavy and innumerable sins that trail behind me are just like this innumerable sand which is trailing behind me, so how can I while still having all these sins of my own judge my brother the monk for his sin? such imitation of Christ with sincerity resulted in the Spirit doing what He has done in the hearts of those who condemned that adulterous woman caught while committing adultery i.e. none of the monks condemned their brother, however because of the hearts of those monks were like fertile ground to bear the Fruits of the Spirit, they not only stopped their condemnation but in complete obedience to the Will of the Spirit, they truly forgave their brother the monk and asked the forgiveness of Abba Moses who is also a Priest that stood with humility foiling the Evil One’s plot to snare the brotherhood in such a deadly snare of spiritual pride.
The seed of wisdom planted by the Holy Spirit on that day still is capable of bearing Fruit,be it 30, 60 or 100 in the hearts of those who love the Son of God who came to call sinners into repentance, Jesus the Savior who would stretch his loving healing hands to touch the leaper the outcast, the reject of society and the world, He who would stand between the accused and the accusers and kneels on dirt to save the condemned. the Eternal who took on for himself the body of a Slave to liberate all captives of sin and death. The Life: who laid down His Life for the life of Sinners whom He loved even unto death and a death that of on the Cross. The Way: who brings the sinners back to the Father in sincere repentance. The Truth: that annihilates all lies that are the brood and snares of death. To all those who worship God not in outside appearances and putting on of airs , but in Truth and Spirit, they bear the yoke and manifest the Image and Likeness of the Son of God who is humble and meek. Those are the Saints!
The Priest Saint Abba Moses imitates Our High Priest, thus he remains the Living Icon of Jesus Christ Crucified and Resurrected! Glory be to God Who is Glorified in His Saints! Amen!
