There are two Catholic churches, a Baptist church, and a Methodist church in St. Marys.

The smaller of the two catholic churches is Immaculate Conception Church, which is a parish church under the jurisdiction of the Roman Catholic Archdiocese of Kansas City.[13]

The largest and newest of the two churches is the Immaculata church, Saint Marys, Kansas, which is under the jurisdiction of the Society of Saint Pius X (SSPX), a traditionalist Catholic association which is in a canonically irregular relationship with the Holy See.[14] The Immaculata was consecrated in a ceremony on May 3, 2023 by Bishop Bernard Fellay, as the final step of a plan written forty-five years prior to the dedication. The New Immaculata Church[15] is one of the largest churches in the state with regular seating for 1,580[16] in order to accommodate the growing community. The building was designed by a team led by David Heit of Civium Architects,[17] from Topeka, Kansas, and constructed by Hutton Construction[18] and BHS Construction.[19]

According to the 2020 census, the majority of St. Marys' inhabitants are Catholics affiliated with the SSPX; this has created tensions with some older residents who are not followers of the movement and who do not share the SSPX's socially conservative values. Tensions also exist between the SSPX-affiliated Catholic community and members of the diocesan Catholic parish of the town.[9]
