They had long conversations together on religion. Casaubon ardently desired a reunion of the Protestants with the Roman Catholics[64]: and would have set about it, had he staid longer in France, as he informed Descordes, who repeated it to Grotius. He greatly respected the opinions of the ancient church[65], and was persuaded its sentiments were more sound than those of the Ministers of Charenton. Grotius and he had imparted their thoughts to each other before the voyage to England: for Casaubon congratulates him, January 8, 1612, on his desiring nothing but peace and a coalition; and communicated Grotius' sentiments to King James; who approved of them. This shews that Grotius thought it was wrong to depart from the discipline and forms of the ancient church: Casaubon was of the same mind; and his Letter to M. de Thou is a demonstrative proof that these two excellent men did not differ in matters of Religion. "I esteem him highly, says he[66], on account of his other great qualities; for he judges of the modern subjects of religious controversy like a learned and good man; and in his veneration for antiquity agrees with the wisest." The last Letter which we have from Casaubon to Grotius comprehends all these sentiments in few words[67]: "I heartily pray God to preserve you ever: and as long as I live, I shall hold you in the highest esteem, so much am I taken with your piety, your probity, and your admirable learning."
