One of the truly great saints of The Church. He is particularly venerated in Orthodoxy. During Great Lent, we say the following Prayer of +Ephraim the Syrian while doing full body prostrations:
O Lord and Master of my life, take from me the spirit of sloth, despondency, lust for power and idle talk.
(Prostration)
But grant unto me, Thy servant, a spirit of chastity, humility, patience and love.
(Prostration)
Yea, O Lord and King, grant me to see mine own faults and not to judge my brothers and sisters. For blessed art Thou unto ages of ages. Amen.
(Prostration)
O God, cleanse Thou me a sinner
(12 times, with as many bows, and then again the whole prayer from the beginning throughout, and after that one great prostration)
