Hence often applied as a party designation to those members of a church or religious sect who hold opinions ‘broader’ or more ‘advanced’ than those in accordance with its commonly accepted standard of orthodoxy, e.g. in Liberal Catholic. Liberal Christian: in the U.S. chiefly applied to the Unitarians and Universalists; in England somewhat more vaguely to those who reject or consider unessential any considerable part of the traditional system of belief; so liberal Christianity, liberal theology. Also in application to Judaism.

5. Of political opinions: Favourable to constitutional changes and legal or administrative reforms tending in the direction of freedom or democracy. Hence used as the designation of the party holding such opinions, in England or other states; opposed to Conservative. Liberal-Labour, of or pertaining to (persons associated with or sympathetic to) both the Liberal and the Labour parties. So Liberal Labourism. Cf. LIB-LAB a.
In Liberal Conservative, the adj. has rather sense 4 than this sense; the combination, however, is often hyphened, which perhaps indicates that it is interpreted as = ‘partly Liberal, partly Conservative.’ Liberal Unionist: a member of the party formed by those Liberals who refused to support Mr. Gladstone's measure of Irish Home Rule in 1886.
