The Church of Scotland (Scots: The Scots Kirk, Scottish Gaelic: Eaglais na h-Alba), known informally by its Scots language name, the Kirk, is the national church of Scotland.[4] Protestantand Presbyterian, its longstanding decision to respect "liberty of opinion in points which do not enter into the substance of the Faith"[5] means it is tolerant of a variety of theological positions, including those who would term themselves conservative and liberal in their doctrine, ethics and interpretation of Scripture.
