This affair seemed almost finished when the Ministers sent to tell him[243] that they would willingly receive him, but not as Ambassador from Sweden, because that kingdom was of a different persuasion.  “I am surprised (he writes to his brother) at the fickleness of people, who invite the Lutherans to partake with them, and say they cannot receive me in quality of Ambassador from Sweden, on account of their differing in opinion from that kingdom.”  To go to sermon as a private man would have been no great inconveniency to him[244], but he could not do this without contradicting his principles, which made him look on the Swedes as orthodox.  He resolved therefore to have Divine Service celebrated for the future in his own house.

It is evident from this recital, which is faithfully taken from Grotius’s letters, that Du Maurier is mistaken in saying[245], that the Ministers of Charenton, when they knew that Grotius was Ambassador from Sweden, deputed one of their number to invite him to their Church; and he answered, that having neglected him when a Fugitive he would now neglect them when Ambassador.

Not having been able to settle matters with the reformed Ministers, he resolved to have Divine Service performed at home.  The Lutherans attended his Chapel as if he publicly professed their religion.  He writes to his brother, Dec. 28, 1635[246], “We celebrated at my house the Feast of the Nativity:  the Duke of Wirtemberg, the Count de Suarsenbourg, and several Swedish and German Lords assisted at it.”

George Calixtus, an eminent Lutheran Minister[247], procured him Brandanus for his Chaplain.  This man was a zealous Lutheran:  Grotius recommended moderation to him, and took him upon condition[248] that he should be upon his guard in his Sermons, and never enter into controversy in public, either with the Roman Catholics or the Reformed.  But his zeal carried him away; and seeing his Master’s Chapel much frequented, he took occasion to rail sometimes against the Papists and even sometimes against the Reformed.  Grotius was much offended at it, not only because it was contrary to agreement, but also because, by publicly attacking in his own house the established Church and the others who were tolerated, he exposed himself to the hatred of the whole kingdom.  He several times intimated to Brandanus[249] to behave otherwise; but his representations and orders having no effect, in autumn, 1637, he forbad him his Chapel:  he kept him however in his house till the end of February following.  To supply the place of Brandanus he pitched upon Francis Dor, who had been deposed at Sedan for his adherence to Arminianism, and since lived by keeping a boarding-school, and teaching French to young Flemings and Germans on their travels in France.  It was some time before he could resolve[250] to quit this manner of life; but at length accepted of Grotius’s offer.  They lived in good understanding together, because their opinions were almost the same.
