While at Berlin, he made several visits to the Netherlands, in 1684, 1686, and 1688, chiefly for the purpose of superintending the printing of several of his works, including the "Traité de la Vérité", 1684. The book went through a vast number of editions and was translated into several languages, an English version, by Henry Lussan, appearing in 1694. Completed by a third volume, the "Traité de la Divinité de Nôtre Seigneur Jésus-Christ", it appeared at Rotterdam, 1689. An English translation, entitled "A Sovereign Antidote against Arian Poyson", appeared in London, 1719, and again "revised, corrected, and, in a few places, abridged", by Abraham Booth, under the title of "The Deity of Jesus Christ essential to the Christian Religion", 1777. The entire apology for Christianity formed by the three volumes of the "Traité", which combated severally the heresies of atheism, deism, and Socinianism, was received with praise. "La Vérité de la Religion Chrétienne Réformée" (1717) was a controversial treatise which in its four parts attacks the characteristic doctrines of the Roman Catholic Church; it was translated into English, for the use of the Roman Catholics of his diocese of Dromore, by Dr. Ralph Lambert, afterwards bishop of Meath. The work was completed in 1723 in "Le Triomphe de la Providence et de la Religion; ou, l'Ouverture des sept Seaux par le Fils de Dieu, où l'on trouvera la première partie de l'Apocalypse clairement expliquée par ce qu'il y a de plus connu dans l'Histoire et de moins contesté dans la Parole de Dieu. Avec une nouvelle et très-sensible Démonstration de la Vérité de la Religion Chrétienne".
