Passage 1:Joyce was ordained priest on 31 October 1930 in the Cathedral of the Blessed Sacrament, Christchurch by his uncle James Byrne, the 1st Catholic Bishop of Toowoomba. He then spent three years in Auckland and was the chaplain at Sacred Heart College, then located in Ponsonby. Joyce returned to Christchurch in 1934 to be assistant priest at Addington and then at Riccarton. In 1937 he was loaned to the Diocese of Toowoomba where he assisted his uncle James Byrne until he died on 11 February 1938. In 1941 Joyce was appointed chaplain to the New Zealand Military Forces and served with New Zealand troops in Tonga and Fiji. In Fiji he was attached to the headquarters of the Fiji Infantry Brigade Group and was associated with many activities for the promotion of the welfare of the troops in his area. After his demobilisation in 1945, Joyce was posted to the reserve of officers with the rank of Major He was stationed at the Cathedral in Christchurch and engaged in rehabilitation work for returned soldiers. He represented Bishop Lyons for three years on the Labour Department immigration committee. At the same time he was involved with general Catholic activities being spiritual adviser to the Catholic Women's League and the Catholic Men's Luncheon Club. Joyce was very involved during the Ballantyne's fire tragedy of 1947 and represented Bishop Lyons at the mass funeral for the victims. Joyce became parish priest at Sockburn in 1947.
Passage 2:From 1983 until Kunstler's death in 1995, Ron Kuby was his junior partner. The two took on controversial civil rights and criminal cases, including cases where they represented Sheikh Omar Abdel-Rahman, head of the Egyptian-based terrorist group Gama'a al-Islamiyah, responsible for the 1993 World Trade Center bombing; Colin Ferguson, the man responsible for the 1993 Long Island Rail Road shooting, who would later reject Kuby & Kunstler's legal counsel and choose to represent himself at trial; Qubilah Shabazz, the daughter of Malcolm X, accused of plotting to murder Louis Farrakhan of the Nation of Islam; Glenn Harris, a New York City public school teacher who absconded with a fifteen-year-old girl for two months; Nico Minardos, a flamboyant actor indicted by Rudy Giuliani for conspiracy to ship arms to Iran; Darrell Cabey, one of the persons shot by Bernard Goetz; and associates of the Gambino crime family.
Passage 3:Austria was subsumed into Germany in 1938. Germany had been governed by Nazis since 1933, according to the twin tenets of populism through the ages: hope and hatred. The hatred was focused on Communists and Jews, and took increasingly sinister and destructive forms. Clara Katharina Pollaczek was subject to antisemitic persecution. She may have owed her survival to her possession of a Czechoslovak passport, acquired as a result of the marriage to Pollaczek. Two days after German troops were welcomed by cheering crowds into Vienna marking Austria's incorporation into Nazi Germany, she crossed to Prague where she lived for a while. When, in 1939, the Germans completed their occupation of Czechoslovakia, she was visiting friends in Switzerland. She stayed in Switzerland, receiving financial support from relatives, till war ended in 1945. During this period she became a Roman Catholic. (The last practicing Jew in her family had been her grandfather.) In 1945 she joined her son Karl who had ended up in Gillingham in England, but he was married with children: the home was cramped and, unlike her younger son, Clara did not feel settled in England. It was her brother, the lawyer Otto Loeb, who organised her return to Vienna in 1948.
