Lasallian educational institutions are educational institutions affiliated with the De La Salle Brothers, a Catholic religious teaching order founded by French priest Saint Jean-Baptiste de La Salle, who was canonized in 1900 and proclaimed by Pope Pius XII as patron saint of all teachers of youth on May 15, 1950. In regard to their educational activities, the Brothers have since 1680 also called themselves "Brothers of the Christian Schools", associated with the Institute of the Brothers of the Christian Schools; they are often referred to by themselves and others by the shorter term "Christian Brothers", a name also applied to the unrelated Congregation of Christian Brothers or Irish Christian Brothers, also providers of education, which commonly causes confusion.
The Chicago Catholic League (CCL) is a high school athletic conference based in Chicago, Illinois, United States.

Men's colleges in the United States are primarily, though not exclusively, those categorized as being undergraduate, bachelor's degree-granting single-sex institutions that admit only men. In the United States, male-only undergraduate higher education was the norm until the 1960s. The few remaining well-known men's colleges are traditional independent liberal arts colleges, though at present the majority are institutions of learning for those preparing for religious vocations, primarily in the Roman Catholic and Orthodox Jewish religious traditions.
Mesivta is an Orthodox Jewish yeshiva secondary school for boys. The term is commonly used in the United States to describe a yeshiva that emphasizes Talmudic studies for boys in grades 9 through 11 or 12; alternately, it refers to the religious studies track in a yeshiva high school that offers both religious and secular studies.
Many American sports team names and mascots are based upon or use religious symbolism. The majority are scholastic teams at institutions founded by various denominations of Christianity, both Catholic and Protestant. Saints is the most popular of these names not only at religious schools but public schools. However, the latter are often indirect, the schools being located in places named for saints. The only team name that has become controversial is Crusaders, many having changed in recent years. The term, once associated with protectors of the faith is now also associated with oppression. Many Christian schools use "Knights" as their team names with imagery similar to crusaders, but it is difficult to establish religious symbolism in these cases. There are also a number of teams whose name includes demons or devils, which are mythological creatures from many cultures. However, the devil imagery in sports used by professional sports teams as well as public and non-sectarian schools are an example of the Devil in the arts and popular culture more than religion. There are also a few team identities based upon Norse mythology in popular culture.
Monsignor Bonner High School was an all-male Augustinian Catholic High School in the Roman Catholic Archdiocese of Philadelphia. It was located in Upper Darby Township, Pennsylvania.

The previously occupied building became the all-female Archbishop Prendergast High School. In 2012, Bonner merged with the all-girls Archbishop Prendergast High School to form Monsignor Bonner and Archbishop Prendergast High School. The Order of St. Augustine is no longer associated with the combined institution.
