""The ""Laws and Constitutions of the Loyal Orange Institution of Scotland"", 1986 state: ""No ex-Roman Catholic will be admitted into the Institution unless he is a Communicant in a Protestant Church for a reasonable period."" Likewise the ""Constitution, Laws and Ordinances of the Loyal Orange Institution of Ireland"" (1967) state: ""No person who at any time has been a Roman Catholic.... shall be admitted into the Institution, except after permission given by a vote of seventy five per cent of the members present founded on testimonials of good character . . . ""(39) In the 19th century, Rev. Dr. Mortimer O'Sullivan, a converted Roman Catholic was a Grand Chaplain of the Orange Order in Ireland.

In the 1950's Scotland also had a converted Roman Catholic as a Grand Chaplain - Rev. William McDermott""
