O Christ our God, the wisdom, power and glory of the Father who didst visibly appear to all men as the Word made flesh, and having overcome the prince of darkness, didst return to thy throne on high: Grant to us thy supplicants, amid this dark world, the full outpouring of thy splendour, and appoint thy holy angels to be our defenders, to guard our going out and coming in, till we take our place at thy right hand; where thou livest and reignest with the Father and the Holy Ghost, ever one God, world without end.
