Ecological Movement of Thessaloniki: Ecological Movement of Thessaloniki (Greek: Οικολογική Κίνηση Θεσσαλονίκης , "Oikologiki Kinisi Thessalonikis"), is the oldest living eco-political group of Greece.  It was founded in 1982, by an initial core of people with ecological sensitivities who wanted to turn them into action.  Among them was Michalis Tremopoulos (currently an elected councillor in the Thessaloniki Prefecture and an elected member of the Executive Secretariat of Ecologist Greens, the Greek Green Party) and Yiannis Tziolas, who are still active.  Oikologiki Kinisi in fact means ecological move or action or movement.  This shows an emphasis on action and social mobilization.  The political agenda of the group consists of the main pillars of the green ideology: ecology, peace/non-violence, grassroots democracy, human rights, social solidarity, with a strong social context.  A major influence was Murray Bookchin's social ecology.  André Gorz, Ivan Illich and Cornelius Castoriadis were also significant influences.

Peter Wilkinson (priest): 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.

William Matthews (priest): 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.

William N. McNulty: Dean (Christianity) William N. McNulty (1829-1922), was an American pioneer Roman Catholic priest, who arrived in New York from his native Ballyshannon, Ireland in 1850, during the time of the Great Irish Potato Famine and when, there, then, existed little in the way of Roman Catholic facilities about near by Passaic County, New Jersey.  He is responsible for much of the foundation of the structural and institutional infrastructure of today's Roman Catholic Church in Paterson, New Jersey.  To the end of his 93 years, a simple parish priest and caring steward of his flock, he refused the Pope's appointment of him as a Domestic prelate and, even, the then powerful Ku Klux Klan could not intimidate this beloved priest's honored 1922 burial.  Father "Mac" as he was affectionately known in Paterson was so revered by its Irish and German Roman Catholic communities that his mere admonishing appearance in midst of Passaic County's 1880 Garret Rock May Day Riot or what national newspaper coverage of the time called "the most serious riot that has ever occurred in that section of the country" was sufficient to permit police to thereafter act to end the rioting.  During his lifetime, the Pope, anyway, accorded this truly Reverend Father the extraordinary honor of naming him to the office of Papal chamberlain, which office is normally the reserve of European nobility.  Father McNulty lies in front of Paterson's St. John's Church under an honoring bronze monument of his counseling a parish youth.

Antoni Klawiter: 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.

Andrew Burnham (priest): Andrew Burnham (born 19 March 1948) is an English priest of the Roman Catholic Church.  Burnham was formerly a bishop of the Church of England and served as the third Bishop of Ebbsfleet, a provincial episcopal visitor in the Province of Canterbury from 2000 to 2010.  He resigned in order to be received into the Roman Catholic Church.  He was ordained as a Roman Catholic priest for the Personal Ordinariate of Our Lady of Walsingham on 15 January 2011.
