A Brief HistoryThe Diocese of Amarillo has a rich and enduring Catholic heritage that traces back to the earliest explorations of the American Southwest. Spanning 26 counties and approximately 25,800 square miles in the Texas Panhandle, the diocese stands as a testament to centuries of missionary zeal, cultural growth, and steadfast faith. Rooted in the early evangelization efforts of Spanish missionaries and formally established in the 20th century, the Diocese of Amarillo continues to proclaim the Good News of Jesus Christ to all its neighbors, honoring its past while looking with hope to the future. -

Coronado's Exploration
The Catholic presence in the Texas Panhandle dates back to 1541, when Spanish explorer Francisco Vásquez de Coronado traversed the region in search of the mythical Seven Cities of Gold. Accompanying him was Father Juan de Padilla, a Franciscan friar who celebrated Mass near present-day Palo Duro Canyon on the Feast of the Ascension. Father Padilla is recognized as the first Christian martyr on what is now U.S. soil, having been killed in 1544 while evangelizing Native peoples in present-day Kansas.

Formal Establishment
Over the centuries, the region fell under various ecclesiastical jurisdictions, including the dioceses of Guadalajara and Linares in Mexico, and later New Orleans, Galveston, and Dallas in the United States. The Diocese of Amarillo was officially established by Pope Pius XI on August 3, 1926, carved from territories of the Dallas and San Antonio dioceses.
Reverend Rudolph Gerken was appointed as its first bishop and was installed at Sacred Heart Church in Amarillo on April 27, 1927. Under his leadership, the diocese saw the construction of numerous churches and the founding of Price Memorial College.
