The duplicity and perfidy of the Emperor and the Romanists in their dealings with the Lutherans was characterized by Chancellor Brueck as follows: "The tactics of the opponents in offering a copy [of the Confutation] were those of the fox when he invited the stork to be his guest and served him food in a broad, shallow pan, so that he could not take the food with his long bill. In like manner they treated the five electors and princes, as well as the related cities, when they offered to accede to their request and submit a copy to them, but upon conditions which they could not accept without greatly violating their honor." (Koellner, 419.) Over against the Emperor's demand of blind submission and his threat of violence, the Lutherans appealed to their pure Confession, based on the Holy Scriptures, to their good conscience, bound in the Word of God, and to the plain wording of the imperial manifesto, which had promised discussions in love and kindness. In an Answer of August 9, _e.g._, they declared: The articles of the Augustana which we have presented are drawn from the Scriptures, and "it is impossible for us to relinquish them with a good conscience and peace of heart, unless we find a refutation founded on God's Word and truth, on which we may rest our conscience in peace and certainty." (Foerstemann, 2, 185.) In the Preface to the Apology, Melanchthon comments as follows on the demand of the Romanists: "Afterwards, negotiations for peace were begun, in which it was apparent that our princes declined no burden, however grievous, which could be assumed without offense to conscience. But the adversaries obstinately demanded that we should approve certain manifest abuses and errors; and as we could not do this, His Imperial Majesty again demanded that our princes should assent to the Confutation. This our princes refused to do. For how could they, in a matter pertaining to religion, assent to a writing which they had not been able to examine, especially as they had heard that some articles were condemned in which it was impossible for them, without grievous sin, to approve the opinions of the adversaries?"
