Smalcald Articles– Part III, Article XII. Of the Church
1] We do not concede to them that they are the Church, and [in truth] they are not [the Church]; nor will we listen to those things which, under the name of Church, they enjoin or forbid. 2] For, thank God, [to-day] a child seven years old knows what the Church is, namely, the holy believers and lambs who hear the voice of their Shepherd. For the children pray thus:I believe in one holy [catholic or] Christian Church. 3] This holiness does not consist in albs, tonsures, long gowns, and other of their ceremonies devised by them beyond Holy Scripture, but in the Word of God and true faith.
