Upon graduation, Teeling became a journalist and travelled widely both at home and abroad, especially in the United States where he described himself as an "amateur tramp". He lived among the homeless and hitched lifts on freight trains, reporting back to The Times about his adventures.
In the early 1930s, he studied the youth movements in Nazi Germany. In winter 1933, Teeling had walked all the way from London to Newcastle upon Tyne, sleeping in hostels and examining the efforts of local councils to tackle unemployment.
Another preoccupation when Teeling was travelling abroad was the treatment given to Irish immigrants and to the Catholic Church. In 1937, he wrote The Pope in Politics (expressively dedicated "to those Catholics who have faith in the future of democracy"), which suggested that Pope Pius XI was opposed to the new forms of Catholicism developing in the Americas and also pointed out the Pope's autocratic views and his complicity with Fascist Italy.[1]
He followed this in 1939 with Crisis for Christianity, a book which dealt with the relations between the Catholic Church and Nazism.
Throughout his Parliamentary career Teeling remained on the backbenches and maintained a close comradery relationship with Sir Winston Churchill.
A keen Orientalist and collector, his expertise on foreign affairs was well acknowledged amongst his peers, (he was a Freeman of Seoul in Korea). He was also a strong supporter of The Republic of China (Taiwan) and a friend of Madame Chiang Kai-Shek. The President of The Republic, Chiang Kai-Shek, presented Dr. Teeling with the Gin-Shin Medal (Order of the Brilliant Star) on 29 November 1959 for his "Achievements and Contributions" to the Republic of China. He maintained a residence near Keelung on the Island of Taiwan and received many gifts from Madame Chang Kai-Shek, including many modest Chinese and Japanese works of art, as she and her friends decorated his home there.
Together with his private secretary, Vera Kaspar, he was a long time supporter of the attempts to build a tunnel under the English Channel, and chaired an all-party committee which campaigned for it. He was also Secretary of the All-Party committee on holiday resorts.
He was knighted in 1962. By 9 July 1968, he was a Member of the Conservative Monday Club and is mentioned as one of the MPs who signed a House of Commons Order Paper (no.151) calling for the government to "exclude all questions of sovereignty over the Falkland Islands from any talks they are having with the Argentine Government".[2]
Teeling resigned in February 1969, owing to ill health. He maintained a Grace and Favour residence in St James', London, and travelled to Africa to help his recovery. He became secretary of the Irish Peers Association in June 1970, whose cause he had often promoted. He bequeathed much of his collection of oriental objets d'art to his private secretary, Vera Kaspar.
