Not one newly taken into the church, for fear that, through his high opinion of himself, he may come into the same sin as the Evil One.

Not a novice, lest being lifted up with pride he fall into the condemnation of the devil.

not a new convert, lest being puffed up he fall into the same condemnation as the devil.
