General Councils may not be gathered together without the
commandment and will of Princes. And when they be gathered
together, (forasmuch as they be an assembly of men, whereof all be
not governed with the Spirit and Word of God,) they may err, and
sometimes have erred, even in things pertaining unto God. Wherefore
things ordained by them as necessary to salvation have neither
strength nor authority, unless it may be declared that they be
taken out of holy Scripture.
