Formerly titled "An Answer to a Letter Written by James Tyrie, A Scottish Jesuit, 1572."

The editor of Knox's writings in the series of British Reformers describes this work as, "among the most interesting of the writings of the Scottish Reformer. The sophistries of the Jesuit are completely exposed, and we have answers to many of those arguments which the Jesuits of the present day have brought forward dressed up in specious colours. The ardent desire of Knox to depart and to be with Christ is fully expressed; and the impartial reader of the letter to Tyrie, with its appendages, will be fully satisfied that Knox was not the turbulent ambitious character which his adversaries represent him to have been."

Knox, in his old age, remains steadfast and fearless, proclaiming that, "the doctrine of the Papistical Church, now many years bypast, hath been altogether corrupt; that their opinion, which they call their Catholic faith, has no sure ground within the work of God; and that the way, which they for the most part have followed, was the very way of perdition to all such as without true repentance departed this life in that blindness; and much more shall be to all persons and estates that now shall maintain those abominations, because the light is come, and has sufficiently declared the former darkness."

This piece should prove useful in our day, as Rome seems to have received a new infusion of power from that Satanic spirit that animates her spiritual fornication and adultery with the nations of the Earth.

A number of so-called "evangelicals," even now, drink from her polluted cup, and others, having entered into the inner chambers of her brothel, lay within this harlot's bosom, having turned from the truth to serve Satan's lieutenant, the Pope of Rome.
