Troparion of St Trea tone 3
Angels rejoiced in thy life of prayer, fasting and seclusion/ for the
love of Christ our Saviour, O holy Trea./ Aware of our worldliness and
lack of resolution,/ we turn to thee, O blessed one, beseeching thee to
intercede for us with Christ our God that He will grant us great mercy.
