Lubbert(us), Librand(us), a Reformed clergyman and professor of divinity at Franecker, was born at Longoworde, Friesland, in 1556, and was educated at Wittenberg University, where he gained great perfection in Hebrew. Afterwards he diligently attended the lectures at Geneva, and still later went to Neustadt, to hear the Calvinistical professors. Lubbert then entered the ministry, and accepted a call to the Reformed Church of Brussels; later he removed to Embden. In 1584 he went to Friesland as preacher to the governor and deputies of the provincial states, and also read lectures on divinity at Franecker University, then just opened. He received the title of D.D. from Heidelberg University. In the controversies concerning the Scriptures, the pope, the Church, and councils, he wrote against the celebrated divines Bellarmine, Gretserus, Socinus, Arminius, Peter Bertius, Vorstius, and Grotius's Pietas Ordineum Hollandiae. He preached zealously, pointedly, and eloquently against all the evils of his times, both in the Church and out of it. He observed the statutes severely, and sometimes refused rectorships because of the debauchery of unreformable scholars. He died at Franecker January 21, 1625.
