In 1928, Jurgens was appointed by Pope
Pius XI as
Bishop of Tuguegarao. He was consecrated bishop by Bishop Arnold Frans Diepen of Hertogenbosch, together with Bishops Pieter Adriaan Willem Hopmans and Gilles de Boeck as co-consecrators. Bishop Jurgens' coat of arms bears the motto "" which translates into "To the Eucharistic Jesus though Mary". As bishop, Jurgens conducted formation for their catechists inside his episcopal residence, and published catechetical materials for children. In exchange for his help in financing the construction of the
Christ the King Mission Seminary, in 1933, the
Society of the Divine Word accepted his request to assist in the pastoral care of his diocese. He also convoked the Third Diocesan Catholic Synod in 1935 to discuss matters concerning their pastoral governance. Although he had to close their San Jacinto Seminary in 1932 due to lack of funding, he was able to open the Cagayan Valley Atheneum, an all-boys school in Tuguegarao, in 1938. After the war, the school was managed by the
Jesuits and converted it as
Ateneo de Tuguegarao, until its closure in 1962. During World War II, Jurgens was among the clergy who were interned at the
Los Baños Internment Camp. He lived together with the other religious who were sent in the camp as civilian internees.
Apostolic Delegate Guglielmo Piani then formed the Prelate Nullius Los Baños Internment Camp to accommodate the spiritual needs of the interned clergy and civilian faithful. After the war, he led the reconstruction of Catholic-owned structures damaged by
World War II.. In 1948, he invited the
La Salette Missionaries to minister in
Isabela due to the lack of priests in the said province. ==Retirement and death==
