IRISH PENAL LAW - SOURCE
Source: Abridgement-Oaths, sec. 18; 4 Stats at L, 12, sec.16 and 17. Note that this section requires all of the oaths, as well as the newer oath of abjuration. The English statute of 1 Ann c.17 referred to here is presumably the statute listed in Statutes of the Realm as 1 Ann, stat 2, c.21. Note also that the requirement of receiving the sacrament affected Protestant Dissenters as well as Catholics.
