Canon LVIII.

The Oblation must not be made by bishops or presbyters in any private houses.

Notes.

Ancient Epitome of Canon LVIII.

Neither a bishop nor a presbyter shall make the offering in private houses.

Van Espen.

By “the oblation” here is intended the oblation of the unbloody sacrifice according to the mind of the Greek interpreters.  Zonaras says:  “The faithful can pray to God and be intent upon their prayers everywhere, whether in the house, in the field, or in any place they possess:  but to offer or perform the oblation must by no means be done except in a church and at an altar.”
