while the parliament approved the confession on 27 august 1560, acting outside the terms of the treaty of edinburgh to do so, mary, queen of scots, a roman catholic, refused to agree, and the confession was not approved by the monarch until 1567, after mary's overthrow. it remained the confession of the church of scotland until it was superseded by the westminster confession of faith on 27 august 1647. however, the confession itself begins by stating that the parliament "ratifeit and apprevit [the confession] as wholesome and sound doctrine grounded upon the infallible truth of god's word"; thus, though changes within societies may have diminished its relevance, believers hold that the authority of its statements is rooted not in parliamentary approval but in, as it says, "the infallible truth of god's word". in 1967, it was included in the united presbyterian church in the u.s.a.'s "book of confessions "alongside various other confessional standards, and remains in the current presbyterian church (u.s.a.)'s "book of confessions".
