Removing the Church of Ireland's lisp, speaking the language of Canaan

Then said they unto him, Say now Shibboleth: and he said Sibboleth: for he could not frame to pronounce it right - Judges 12:6.

From Jeremy Taylor's sermon at the funeral of Bramhall, recounting the late Archbishop's work in securing the adoption of the Thirty-Nine Articles by the Convocation of the Church of Ireland in 1634, in place of the Irish Articles of 1614:

He was careful ... to cause the Articles of the Church of England to be accepted as the Rule of publick confessions and persuasions here, that they and we might be Populus unius labii, of one heart and one lip, building up our hopes of heaven on a most holy Faith; and taking away that Shibboleth, which made this Church lisp too undecently, or rather in some little degree to speak the speech of Ashdod, and not the language of Canaan; and the excellent and wise pains he took in this particular no man can dehonestate [i.e. disparage] or reproach, but he that is not willing to confess that the Church of England is the best Reformed Church in the world.
