Paragraph 25.5
Of the Westminster Confession of Faith (1646)
The purest Churches under Heaven are subject both to mixture, and error:1 and some have so degenerated, as to become no Churches of Christ, but Synagogues of Satan.2 Nevertheless, there shall be always a Church on Earth, to worship God according to his will.3
The 1689 Baptist Confession
26.3
The purest Churches under Heaven are subject to mixture, and error; and some have so degenerated as to become1 no Churches of Christ, but Synagogues of Satan; nevertheless Christ always has had, and ever shall have a2 Kingdom in this World, to the end thereof, of such as believe in him, and make Profession of his Name.3
