This is my icon of St Nicholas, it is 19th cent. Russian.
The roundels recall the legend that St Nicholas was imprisoned for beating up Arius, pulling his beard and punching him in the mouth. He heard the great heresiarch speak and couldn't bear hearing his blasphemies, he pulled his beard and punching him in the mouth. The Emperor Constantine was horrified that he should break the peace of the Council and had him deposed.
During the night Christ himself accompanied by his mother appeared to him and asked, "Why are you here?" he answered, "Because I love you, Lord". Christ gave him back the Gospels, the symbol of his teaching authority and his mother the omophorion (the eastern pallium) the symbol of his sacramental authority.
I love St Nicholas because he was so clear in his teaching, the other bishops sat around discussing subtleties and nuances. Holy Nicholas went to the heart of the matter recognising Arius as the enemy of Christ and his Church and indeed the whole of creation and risked all by attacking him.
Holy Nicholas, Bishop of Christ, pray for me a sinner.
Intercede for all the bishops and priests,
that they may recognise Christ and proclaim His Truth for the Salvation of the World.
Make them fearless in denouncing error and the contamination of heresy.
Give them courage, even in the face of the Princes of this World,
to risk all for love of Christ,
the True Bishop and High Priest, the Judge of Souls who will come in Glory.
Lord Jesus give us holy priests and even holier bishops.
