 Let holy water be made, and sprinkled in the said temples; let altars be erected, and let relics be deposited in them.For since those temples are built, it is requisite that they be converted from the worship of the devils to the service of the true God; that the nation, not seeing those temples destroyed, may remove error from their hearts, and knowing and adoring the true God, may the more familiarly resort to the same places to which they have been accustomed.And because they are wont to sacrifice many oxen in honour of the devils, let them celebrate a religious and solemn festival, not slaughtering the beasts for devils, but to be consumed by themselves, to the praise of God...
