See earlier posts comparing latin originals with Mohrmann and Cranmer.
Grant we beseech you O Lord that your people may avoid the temptations of the devil, and with pure minds follow you the only God.
Lord we beseech thee grant thy people grace to avoid the infections of the Devil and with pure heart and mind to follow thee the only God.
Da quaesumus Domine populo tuo diabolica vitare contagia, et te solum Deum pura mente sectari.
I just love the way Cranmer keeps the idea of diabolical Evil as a contagion we catch and pass on. The 1662 Prayer Book - and Mohrmann - mess this up. But there are hundreds of sermons in it.
