“Ecclesia reformata semper reformanda est secundum Verbum Dei” (“The church Reformed and always reforming according to the Word of God.”)

"‘Singing a new song’ and ‘always being reformed’ are only commendable goals if they are invitations to courageous and obedient faith rather than simply following the spirit of the age. It means that the church is always being reformed, not reforming itself, submitting itself to the judgment of God’s Word and asking anew whether its confession and practice are in accord with Scripture. Only in this way is any church truly apostolic" ~Michael Horton
