from The Passion of St. Sergius and Bacchus martyred early 4th century

Meanwhile the blessed Serge, deeply distressed and heartsick over the loss of Bacchus, wept and cried out, "No longer, brother and fellow soldier, will we chant together, 'Behold, how good an pleasant it is for brethren to dwell together in unity!' You have been unyoked from me and gone up to heaven, leaving me alone on earth, bereft, without comfort." After he uttered these things, the same night the blessed Bacchus suddenly appeared to him with a face as radiant as an angel's, wearing an officer's uniform, and spoke to him. "Why do you grieve and mourn, brother? If I have been taken up from you in body, I am still with you in the bond of union, chanting and reciting, "I will run the way of thy commandments, when thou hast enlarged my heart.' Hurry up then, yourself, brother, through beautiful and perfect confession to pursue and obtain me, when finishing the course. For the crown of justice for me is with you."
