Whether he uttered those words or not it was with Calvins encouragement that Michael Servetus burned at the stake in 1553. Not only that but the edict was to use green wood so that it would take longer and a wreath strewn with sulfur was put on his head.
What the Catholics fail to mention is that it was the Catholics who originally convicted Servetus but he escaped only to have Calvin have him arrested again when he recognized him at one of his sermons. So if the Catholics use that line they are denying the Catholic involvement and really only set a trap for themselves. So while I didn’t mention anything about the Catholic complicity I knew that I couldn’t rely on NLs historical accuracy or honesty whichever it was. It helps me understand the reliance of who I am debating. There are some who I don't take too seriously or give much credence to.
"....That Jesus, surnamed Christ, was not a Hypostasis but a human being is taught both by the early Fathers and in Scriptures, taken in their literal sense, and is indicated by the miracles he wrought. He, and not the Word, is also the miraculously born Son of God in fleshly form, as the Scriptures teach - not a hypostasis, but an actual Son. The Holy Spirit as a third person of the Godhead is unknown in Scripture. It is not a separate being, but an activity of God himself. The doctrine of the Trinity can be neither established by logic nor proved from Scriptures, and is in fact inconceivable."

"....For many, Servetus is the ultimate example of the intolerance and cruelty of Calvin. I have no desire to try to justify the persecution or execution of heretics, but in fairness to Calvin the Servetus episode must be seen in historical context. Servetus denied the doctrine of the Trinity, and that was a capital crime almost everywhere in Europe. When Servetus came to Geneva, he had already been sentenced to death in France....Almost all Europeans in Calvin's day believed that heresy was as dangerous as the plague and that civil governments had the obligation to eradicate it....

....Sufficient evidence was found that the "Restitution" had been printed in Vienne; extracts were made from it to prove the heresies contained therein. The civil court, without waiting for the judgment of the spiritual tribunal (which was not given until six months afterwards), sentenced Servetus on the 17th of June, for heretical doctrines, for violation of the royal ordinances, and for escape from the royal prison, to pay a fine of one thousand livres tournois to the Dauphin, to be carried in a cart, together with his books, on a market-day through the principal streets to the place of execution, and to be burnt alive by a slow fire.On the same day he was burnt in effigy, together with the five bales of his book, which had been consigned to Merrin at Lyons and brought back to Vienne.
