And then there is the famous speech by the ""infallible pope"" Urban the second when he sent the catholic crusaders off to take Jerusalem::
"""""... this land which you inhabit, shut in on all sides by the seas and surrounded by the mountain peaks, is too narrow for your large population; nor does it abound in wealth; and it furnishes scarcely food enough for its cultivators. Hence it is that you murder one another, that you wage war, and that frequently you perish by mutual wounds. Let therefore hatred depart from among you, let your quarrels end, let wars cease, and let all dissensions and controversies slumber. Enter upon the road to the
Holy Sepulchre; wrest that land from the wicked race, and subject it to yourselves ... God has conferred upon you above all nations great glory in arms. Accordingly
undertake this journey for the remission of your sins, with the assurance of the imperishable glory of the Kingdom of heaven.""""
Again who needs the Atonement of the LORD Jesus Christ for the remission of ones sins when the (infallible according to catholic dogma) Pope declared that men can provide remission for their own sins by engaging in war against the wicked race of unbelievers..
