This chapter examines the importance of the Protestant Faith and Church and of the Orange Order to UUP members. Whilst overwhelmingly Protestant, the UUP has always rejected the overtly fundamentalist, Free Presbyterian brand with which the DUP was associated for many years. The chapter analyses whether the Church of Ireland or Presbyterian Church provide most UUP members. The chapter then discusses the religiously conservative attitudes of members, assessing the extent of support for, or opposition to, the legalization of same-sex marriage and abortion, currently still prohibited (other than in exceptional cases for abortion) in Northern Ireland. The extent to which members offer support for ‘mixed’ (Protestant–Catholic) marriages and for unfettered marching rights for the Orange Order, will also be examined. Are older members, politically socialized in an era of fraternal Orange–UUP relations, still more sympathetic to the Orange Order? The survey data allow direct comparisons with the DUP.
