The root of popery struck at, and the true ancient apostolick foundation discovered, in some propositions to the papists concerning fallibility and infallibility, which cut down the uncertain, and manifest the certain way of receiving and growing up into the truth : also, some considerations concerning the true and false church and ministry, with the state of each since the dayes of the apostles : held forth in true love and pity to the souls of the papists, that they may hear and consider, and not mistake and stumble at the rock of ages, whereupon the prophets, apostles, and whole flock of God throughout all generations have been built : there is likewise somewhat added concerning the ground of error, and the way to truth and unity, for the sake of such as are more spiritual, and have been more inwardly exercised in searching after truth / by Isaac Penington, the younger.
