Diocese of Cheyenne Menu

Welcome to the Diocese of Cheyenne website!

The Diocese of Cheyenne encompasses the entire State of Wyoming, to include Yellowstone National Park. The rich history of Catholicism in Wyoming began on July 5, 1840, when Father Pierre-Jean DeSmet said the first Catholic Mass near Horse Creek, at the Green River Rendezvous, in present-day Sublette County. Since then, with our Diocese established in 1887, we have grown to 33 parishes and missions. Our state is a land of wide open spaces and sparsely populated towns, but our people are faith-filled and tightly-knit, bound together by a love of God, country, community, and a Western spirit unique to this special place.

We invite you to explore our website and learn more about our Diocese. You will find quick links above to several of the more frequently visited pages within our site. Get to know our clergy, Diocesan officials, upcoming events and retreats, and even the history of our Diocese. All this and more can be found in the main menu at the top of the page.

Please also visit our other Diocesan websites: Hispanic Ministry, Vocations, Catholic Social Doctrine, and Office of the Legislative Liaison.

If you are traveling within Wyoming, you’ll find current information about our parishes & missions, their locations, links to parish websites, and mass times here >>

“For as in one body we have many parts, and all the parts do not have the same function, so we, though many, are one body in Christ and individually parts of one another.”
-Romans 12:4-5

Message from Bishop Etienne
June 26, 2015

I am disappointed with today’s US Supreme Court ruling that requires all states to recognize the union of same sex couples.

Pope Francis recently reminded all people of good will that “every man and woman is created out of love and created in God’s image and likeness.” (cf. Genesis 1:26) (Laudato Si, # 65) This fundamental understanding of the human person and their inherent dignity is intimately linked to our Creator. Certainly, we as members of the Catholic Church will continue to promote and defend the dignity and respect of every person.

The same Creator has also inscribed the truth of marriage in the very body of the human person. This truth of marriage as a union between a man and a woman has been received from the Creator and lived by men and women since the foundation of the world. Such truth never changes. Only human philosophies change over time. Sadly, today’s ruling by the US Supreme Court is one more shift in human thought that will not stand the test of time.

The Catholic Church will continue to preach the dignity of every human person, and invites a respect for all people, despite their own beliefs and practices. At the same time, the Catholic Church will continue to teach the dignity and sanctity of marriage as the loving and fruitful union of one man and one woman.

It is our deepest hope that today’s ruling will in no way allow the government to eventually restrict religious institutions and people of faith from teaching what we believe, and will respect our religious freedom to practice what we teach.
