Grotius’ correspondence from this period clearly shows that his own religious views were veering towards Arminianism and that he supported Oldenbarnevelt and his vision of religious tolerance and co-existence. However, he initially remained reluctant to express these ideas too openly or explicitly. In this letter, he writes Oldenbarnevelt that the subject of the Remonstrants and the English response to the conflict will come up during his diplomatic mission to England in the spring of 1613. King James I, Grotius writes, will want to discuss the issue with him but he is in no hurry (‘nyet te dringhen nochte my te verhaesten’) to do so.
