The education of children, adolescents and young people has long been a focal ministry for Marists. Fr Colin described young people as "God's children that are entrusted to us" and he described the formation of the human person as "a sublime task”. Further, to educate a person in a Christian way was “a heavenly work”, a kind of “second creation”.
He showed himself to be a wise and gifted teacher who had a special love and affection for young people and a deep admiration for the work of education. This ministry continues today through those Marists who work in schools and those with whom they work.
Marists minister as administrators, teachers, counselors and chaplains in schools in a number of countries including Africa, Australia, Canada, Fiji, France, Germany, Ireland, Italy, Mexico, New Zealand, Solomon Islands, Tonga, USA.
In recent years Marist have also become involved in less institutional ways of ministering to youth, especially with concern for those in special need, those marginalized by society, for example: children of asylum seekers, street kids, the handicapped, in Thailand, New Zealand, Africa, Italy.
Another branch of education that Marists have served in over many years has been the education of adults in universities, colleges, and seminaries.
