A short reply to the postscript [electronic resource] : to Mr. Abernethy's defence of the seasonable advice, by the three reverend Dublin ministers: wherein is considered what they offer against the Westminster confession of faith, and the Use of it in Reference to Candidates for the Holy Ministry, as is practised in the North, according to Synodical Resolutions. And likewise what they propose for having ministerial communion allowed among the northern presbyterians, without subscription to the said confession, or Declaration of Assent to the Doctrines of it, is shewed to be inexpedient, and as of dangerous consequence.
