Heretic J.C. Ryle’s Warnings to the churches (last two points, #14 and #15):
14. BECOME THROUGHLY ACQUAINTED WITH THE REFORMATION
“Let us make ourselves thoroughly acquainted with the history of the English Reformation. My reason for offering this counsel is my firm conviction that this highly important part of English history has of late years been undeservedly neglected. Thousands of Churchmen now-a-days have a most inadequate notion of the amount of our debt to our martyred Reformers. They have no distinct conception of the state of darkness and superstition in which our fathers lived, and of the light and liberty which the Reformation brought in. And the consequence is that they see no great harm in the Romanizing movement of the present day, and have very indistinct ideas of the real nature and work of Popery. It is high time that a better state of things should begin. Of one thing I am thoroughly convinced: a vast amount of the prevailing apathy about the Romanizing movement of the day may be traced up to gross ignorance, both of the true nature of Popery and of the Protestant Reformation.”
And:
15. BEWARE OF IDOLATRY
“Let us mark this well. It is high time to dismiss from our minds those loose ideas about idolatry, which are common in this day. We must not think, as many do, that there are only two sorts of idolatry–the spiritual idolatry of the man who loves his wife, or child, or money more than God; and the open, gross idolatry of the man who bows down to an image of wood, or metal, or stone, because he knows no better. We may rest assured that idolatry is a sin which occupies a far wider field than this. It is not merely a thing in pagan lands, that we may hear of and pity at missionary meetings; nor yet is it a thing confined to our own hearts, that we may confess before the mercy-seat upon our knees. It is a pestilence that walks in the Church of the Living Christ to a much greater extent than many suppose. It is an evil that, like the man of sin, “that sets himself up in God’s temple, proclaiming himself to be God” (2 Thessalonians 2:4).”
