'Being driven from the facea of the ground' means being separated from all the truth of the Church. This is clear from the meaning of 'the ground', which in the genuine sense is the Church or member
of the Church, and so whatever the Church professes, as stated already. But as the subject itself determines the precise meaning of all that has reference to it, anyone who professes an erroneous faith,
that is, schism or heresy, is also called 'the ground'. At this point therefore 'being driven from the facea of the ground' means not being governed any longer by the truth of the Church.
