Obedience and Service in the Monastery
At the monastery of Abba Seridus, Dositheus was given charge of the infirmary, where he cared for the sick of the community. His life became distinguished less by extraordinary feats of asceticism than by humility, self-denial, and the gentle, supportive manner with which he tended the ill.
His elder Dorotheus trained him chiefly in the renunciation of self-will, leading him gradually in abstinence and fasting by decreasing each day the quantity of food he consumed. Dorotheus later testified that Dositheus had surpassed his other disciples in virtue without practising any unusual austerity, holding him up as a pattern of obedience.
