'Do not go into the way of the nations, he says, and do
not enter a city of the Samaritans. This is to be understood of the
heretics; then let us not enter their churches, nor their houses; but
where the son of peace is, the seed of true religion, there let us stay,
and there let us pass our time, as in times past. Let us guard
ourselves from those who counterfeit the truth, from those who call
themselves guides and are not guides, but deceivers who both deceive and
are deceived, mislead and are misled, whose condemnation is deserved.
Let us guard the faith unswerving and our way of life intact, not
maltreating the one by the other, but being safe and perfect on either
hand.'
