The Linacre Quarterly is a peer-reviewed academic journal that was established in 1932.
 It is the official journal of the Catholic Medical Association and primarily focuses on the relationship between medicine and spirituality, and in particular on medical ethics.
 The journal is named after Thomas Linacre, the English physician and Catholic priest, who founded the Royal College of Physicians.
 Since 2013, it is published by Maney Publishing on behalf of the Catholic Medical Association.
Rev. Lucyan Bójnowski (February 5, 1868 - July 28, 1960) was a Polonia activist and Catholic priest who served as pastor in New Britain, Connecticut.
 He grew up in a noble family in Świerzbutów, Poland from which he gained a strong sense of public service for the less fortunate.
 He escaped Poland under Russian occupation to avoid conscription.
 He arrived in the United States in 1888 and studied at Saints Cyril and Methodius Seminary at Orchard Lake, Michigan, a highly-Polish settlement at the time.
 He became an ordained priest and led the construction of Sacred Heart Parish in New Britain, Connecticut.
 He drew many parishioners and Polish immigrants flocked to his growing church, expanding its construction and design.
 A Polish bank, printing operation, and newspaper were started within his church.
 He fought against a growing dissatisfaction with the Catholic Church among his parishioners, who wanted to establish an independent church like the Polish National Catholic Church.
 He was vocal in fighting back against these voices, and remained an influential voice of Polonia, although at odds with Francis Hodur and the Polish National Catholic Church.
 John B. Frantz of the Pennsylvania State University identifies Bojnowski as entirely "pragmatic" in that he stayed loyal to the Catholic Church despite his own aversion to the Irish and German domination because he viewed Polish leadership as possible, and wanted to "substitute his own strong leadership for that of an alien bishop."
 He never reached the status of bishop, but his influence was felt among Polonia politically.
 He was very active in Polish issues nationally and recruited Polish parishioners for World War I and World War II.
 His influence among Polonia had decreased by the time of World War II, according to historian James S. Pula, who wrote, "his often unbecoming rhetoric helped to drive further wedges in Polonia at the expense of unity in support of Poland."
Concilium is an academic journal of Roman Catholic theology.
 It was established in 1965 and is published five times a year.
 The journal was established by Anton van den Boogaard, Paul Brand, Yves Congar, Hans Küng, Johann Baptist Metz, Karl Rahner, and Edward Schillebeeckx.
 It is published in six languages: Croatian, English, German, Italian, Portuguese, and Spanish.
William Matthews, S.J. (December 16, 1770 – April 30, 1854) was an American Roman Catholic priest of the Society of Jesus from Maryland.
 He was the first person born in British America to be ordained a Catholic priest and was the fifth Catholic priest in the United States.
 In 1809, Matthews became the seventh President of Georgetown College in Washington, D.C., which later became Georgetown University.
Hans Küng (] ; born 19 March 1928) is a Swiss Catholic priest, theologian, and author.
 Since 1995 he has been President of the ("Stiftung Weltethos").
 He is notable for his rejection of the doctrine of papal infallibility.
 Although Küng is not officially allowed to teach Catholic theology, his priestly faculties have not been revoked.
 In 1979, he had to leave the Catholic faculty, but remained at the University of Tübingen as a professor of ecumenical theology, serving as an emeritus professor since 1996.
James Augustine Healy (April 6, 1830 – August 5, 1900) was an American Roman Catholic priest and the second bishop of Portland, Maine; he was the first bishop in the United States of any known African descent.
 Born in Georgia to a mixed-race slave mother and Irish immigrant father, he identified and was accepted as white Irish American, as he was half Irish and majority European ancestry.
 When he was ordained in 1854, his mixed-race ancestry was not widely known outside his mentors in the Catholic Church.
 (Augustus Tolton, a former slave who was publicly known to be black when ordained in 1886, is sometimes credited as the first black Catholic priest in the U.S.)
Monsignor Peter Wilkinson (born 1940) is a Canadian Roman Catholic priest.
 He was formerly a bishop in the Anglican Catholic Church of Canada, a Continuing Anglican church within the Traditional Anglican Communion.
 He was received into the Roman Catholic Church in 2012 and was ordained a Catholic priest and serves within the Personal Ordinariate of the Chair of Saint Peter.
Fr.
 Marcelline Jayakody (Sinhala: මර්සලින් ජයකොඩි පියතුමා) (3 June 1902 ─ January 15, 1998) was a Sri Lankan Catholic priest, musician, lyricist, author and journalist and an exponent of indigenous culture.
 He is attributed with the epithet 'පන්සලේ පියතුමා' (Pansale Piyathuma - Priest in the Temple).
 Ven.
 Dr. Ittapane Dhammalankara Thera authored a book on the life of Fr.
 Mercelline Jayakody, 'මල් පැලේ උපන් පන්සලේ පියතුමා' (‘Malpale Upan Pansale Piyathuma’) which is recorded as the first book in the world by a Buddhist prelate on a Catholic priest.
Tomáš Petráček (born 1972 in Hořice v Podkrkonoší) is a Czech public intellectual, Roman Catholic priest, and scholar.
 He is considered one of country's leading church and social historians.
 He works at the Department of Cultural and Religious Studies at the Faculty of Education at the University of Hradec Králové in East Bohemia, and at the Institute for the History of Christian Art at the Catholic Theological Faculty of Charles University in Prague.
 He is the author of seven monographs and more than 80 articles, studies and papers not only in Czech, but also in English, French, German and Polish.
 He is an active member of the editorial board for the Czech journal Salve, which deals with theological, historical, philosophical and cultural themes.
 As a Roman Catholic priest he serves as chaplain of the academic community in Hradec Králové.
 In 2010, he was appointed Canon of the Chapter of All Saints at Prague Castle, founded in 1339 by Emperor and King Charles IV for professors of the Charles University.
Antoni Klawiter, the Roman Catholic and, afterward, independent Polish Catholic priest, was born in Chojnice, in modern Poland, on November 12, 1836.
 The scholarly consensus is that he was the son of Polonized Germans; by virtue of his Kashubian birthplace and his later experience pastoring Kashubians in Winona, Minnesota, he will not have been unfamiliar with the Kashubian culture.
 In 1859, he was ordained a Roman Catholic priest in Włocławek, and became four years afterward one of many Polish priests who were involved with the Polish Insurrection of 1863.
 In late 1873 or early 1874, Father Klawiter emigrated to the United States.
