A serious and humble enquiry whether it be lawful, [electronic resource] : prudent, or convenient, that a toleration of Popery should be enacted by Authority of Parliament? Or, whether speedy and effectual Measures ought not rather to be taken, to suppress the Growth and Encrease of that superstitious and idolatrous Way of Worship, as highly dangerous to the True Religion establish'd amongst us; to the Protestant Succession in the Illustrious House of Hanover and the True Protestant Interest of this Kingdom of Ireland. Together with an answer to an anonymous letter, on the subject of my letter and reply to Mr. Synge's sermon and vindication. By Stephen Radcliffe, A. M. Vicar of Naas.
