This plan was well conceived: it now remained to be put in execution, and for that purpose it was necessary to persuade the Protestants that such a method would be the surest for them. The person selected for this intrigue was Alphonso Valdez, secretary to Charles V., a Spanish gentleman, a worthy individual, and who afterwards showed a leaning towards the Reformation. Policy often makes use of good men for the most perfidious designs. It was decided that Valdez should address the most timid of the Protestants—Melancthon.

On the 16th or 17th of June, immediately after the arrival of Charles, Valdez begged Melancthon to call on him. "The Spaniards," said he, "imagine that the Lutherans teach impious doctrines on the Holy Trinity, on Jesus Christ, on the blessed Mother of God.[506] Accordingly, they think they do a more meritorious work in killing a Lutheran than in slaying a Turk."

"I know it," replied Melancthon, "and I have not yet been able to succeed in making your fellow-countrymen abandon that idea."

"But what, pray, do the Lutherans desire?"

"The Lutheran question is not so complicated and so unseemly as his majesty fancies. We do not attack the Catholic Church, as is commonly believed;[507] and the whole controversy is reducible to these three points. The two kinds in the sacrament of the Lord's Supper, the marriage of pastors, and the abolition of private masses. If we could agree on these articles, it would be easy to come to an understanding on the others."

"Well, I will report this to his majesty."

Charles V. was charmed at this communication. "Go," said he to Valdez, "and impart these things to the legate, and ask Master Philip to transmit to you in writing a short exposition of what they believe and what they deny."

Valdez hastened to Campeggio. "What you relate pleases me tolerably," said the latter. "As for the two kinds in the sacrament, and the marriage of priests, there will be means of accommodation;[508] but we cannot consent to the abolition of private masses." This would have been in fact cutting off one of the greatest revenues of the Church.

On Saturday, June 18, Valdez saw Melancthon again. "The Emperor begs of you a moderate and concise exposition," said he, "and he is persuaded that it will be more advantageous to treat of this matter briefly and privately,[509] avoiding all public hearing and all prolix discussion, which would only engender anger and division."—"Well," said Melancthon, "I will reflect upon it."

Melancthon was almost won over: a secret conference agreed better with his disposition. Had he not often repeated that peace should be sought after above all things? Thus everything induced the legate to hope that a public struggle would be avoided, and that he might be content, as it were, to send mutes against the Reform, and strangle it in a dungeon.[510]
