Noll was ordained a priest on June 4, 1898, for the Diocese of Fort Wayne by Bishop Joseph Rademacher.
Noll would ask them to prove their identify by asking the name of their religious order or by requesting the recitation of a specific prayer.
Noll bought a printing press and in 1912 founded the weekly newspaper Our Sunday Visitor (OSV) It became widely distributed at many parishes as a supplement or in coordination with the local paper.
[2] As a bishop, he built a preparatory seminary, several high schools, and an orphanage, and during the Great Depression reorganized the system of Catholic charities.
[6] Noll was strongly associated with conservative elements of the Church during his career as a journalist and churchman, linking arms with the more rabid end of the anti-communist movement in the United States and elsewhere.
This included condemnation of many labor unions—much to the chagrin several fellow bishops—and collaboration with the infamous radio priest Charles Coughlin.
