Christine Mohrmann (whom I usually praise to the skies) provided this translation of the Collect in the Tridentine Missal for Pentecost 17:
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.
Cranmer (1549) rendered it thus, from Trinity 18 in the Sarum Missal:
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.
Here is the Latin original as provided by S Pius V:
Da quaesumus Domine populo tuo diabolica vitare contagia, et te solum Deum pura mente sectari.
I just love the way Cranmer kept the idea of diabolical Evil as a contagion or infection which we catch and pass on. The 1662 Prayer Book, followed by Mohrmann, mess this up. But there are hundreds of sermons in it.
