Johannes Hoornbeek[1] (4 November 1617, Haarlem – 23 August 1666, Leiden), was a Dutch Reformed theologian.
The two universities were closely related in the 17th century, and both the teacher and his students participated in the intellectual "Utrecht Circle."
A collection of his polemical writing was the Summa Controversiarum Religionis; Cum Infidelibus, Hæreticis, Schismaticis: Id Est, Gentilibus, Judæis, Muhammedanis; Papistis, Anabaptistis, Enthusiastis et Libertinis, Socinianis; Remonstrantibus, Lutheranis, Brouvnistis, Græcis of 1653 (second edition, 1658).
He also wrote "a fierce critique of Judaism in general and of the Kabbalah in particular," advocating the conversion of the Jews to the Dutch Calvinist/Reformed Church.
The book Tesjubat Jehuda sive pro convicendis et convertendis Judaeis Libri Octo was published in Leiden in 1655.
