Lubieniecius Stanislaus , (Polon. Lubienietzki, or Lubieniecki,) was a Polish Knight, and brother of Andrew, whose junior he was by about seven years ; and in imitation of whom, he relinquished the pleasures and attractions of a Court, and undertook the office of a Pastor among the Unitarians. In the year 1577, he was a Page at the Court of Stephen Bathory, King of Poland; and, while in that station, was converted to Unitarianism, by hearing a sermon of George Schomann, On the Son of God and the Holy Spirit. He was Minister successively at Troppau, Racow and Luclavice. In the Synod held at Lubelsk, A. D. 1612, he, together with some other Ministers and Members of the Church, sought a union with the Evangelical party ; and he subscribed the proposals, sent in on this occasion, in the following manner. "Stanisl. Lubieniecki, Coetus Luclavicensis Superintendens." He died in the year 1633, at the age of seventy-four, or seventy-five. The manuscript Synodical Acts mention a Sermon, which he delivered at the Synod of Racow in 1631, a year or two before his death. An account of his writings is subjoined.

1. Various Polish Songs. Among these was a spirited Ode, which was inserted in the Collection of Psalms and Hymns, used by the Polish Unitarians.

2. Spiritual Preservatives ; in the Polish language.

3. The Precursor of the Last Judgment of the Lord.

4. A work in the Polish language, Against John Petricius. In this work, he says, "Christ obtained this advantage from his suffering and death, that he was presented by God with a happy immortality ; in which respect he was like us, who manifestly obtain the same advantage from his suffering and death, although Christ obtained it before us all."

5. A Catechism, or Brief Compendium of the Doctrine of the Polish Unitarian Church ; usually attributed to his nephew of the same name, but probably written by himself.
