XX. Of the Authority of the Church.
The Church hath power to decree Rites
or Ceremonies, and authority in Controversies of Faith: and yet it is not
lawful for the Church to ordain anything that is contrary to God's Word
written, neither may it so expound one place of Scripture, that it be
repugnant to another. Wherefore, although the Church be a witness and a
keeper of Holy Writ, yet, as it ought not to decree any thing against the
same, so besides the same ought not to enforce any thing to be believed for
necessity of Salvation.
