[1] He later became a columnist of L'Osservatore Romano,[1] receiving the task of talking about the foreign affairs[2] by Bishop Giovanni Montini, the future Pope Paul VI.

On 3 September 1939, a few days after the beginning of World War II, Gonella was arrested by the fascists and brought to Regina Coeli, being freed only after the intervention of Pope Pius XII.

Before the World War II, Gonella began to work with Alcide De Gasperi[3] and took part in the drawing of the Code of Camaldoli, the document planning of economic policy by members of the Italian Catholic forces.

[4] In 1943, Gonella joined the new-born party Christian Democracy,[5] with which he was elected to the Constituent Assembly in 1945, to the Chamber of Deputies from 1948 to 1968 and to the Senate from 1972 to 1979.

[8] Gonella died in Nettuno, near Rome, at the age of 76, on 19 August 1982, exactly 28 years after the death of Alcide De Gasperi.
