Grotius foresaw that his Commentary on the New Testament would occasion him some disputes. "I am at a loss, says he, to Vossius, what to do with my Notes on the New Testament. I shall easily find a bookseller here; but I am afraid of meeting with some difficulties from the Divines, who will have nothing of this kind published without their approbation: and for my own part, I cannot submit in every thing to either of the two parties, nor can I be silent when I have something that may be of use to deliver. I shall see how to remedy this inconveniency. I have no hopes, says he to his brother[512], that the Divines of the Sorbonne will give their approbation to my Notes, especially since they censured Milletiere. It remains to be considered whether I shall print them in my own house without approbation, of which there have been examples." Heinsius's work, which was expected with so much impatience, had no success[513]. Salmasius (his declared enemy indeed) said publicly, he was ready to shew, that, abstracting what he had borrowed, there would not remain one remark of importance: and it was held in no higher esteem by others of the first rank in learning[514]. Cardinal Richelieu, being informed that Grotius leaned more to the sentiments of the Roman Catholics, than to those of the Ministers of Charenton, gave orders[515] that his work should be printed without being obliged to pass the censors. He kept measures however with Heinsius; and desired his brother William Grotius to tell him[516], that he had always said there were several things in his Notes which pleased him much; and that he had made the same remarks in some places that Heinsius had done, by mere chance. As Grotius had a very great esteem for the learned Father Petau, he communicated to him his works. On sending him his Notes on the Old Testament, he desired him to hint what alterations he thought necessary.
