In 1921 Tiso was appointed Monsignor by the Vatican, although this appointment lapsed with the later death of Pope Benedict XV. From 1921 to 1923, he served as the secretary to the new Slovak bishop of Nitra, Karol Kmeťko. During the same period, nationalist political agitation earned Tiso two convictions by the Czechoslovak courts for incitement, one of which resulted in a short incarceration. Displeased, Kmeťko dropped him as secretary in 1923, but retained him as a Professor of Theology. In 1924, Tiso left Nitra to become dean of Bánovce nad Bebravou. He remained the Dean of Bánovce for the rest of his political career, returning there regularly every weekend also as a Czechoslovak minister, and as later as president.
