Thomas Lønborg-Jensen had been in England in 1926 and was influenced by the life of the Anglican ordinands of Kelham Theological College, operated by the Society of the Sacred Mission.
[1] The circle of founding brothers included Regin Prenter, Richard Fangel, and Dag Monrad Møller.
The organisation of the Theologisk Oratorium is simple; there is no corporate Chapter, but only a Leader of the Brotherhood, and local superiors of the regional conventions.
The daily office, private confession, the Eucharist, and reading of theology are important parts of the common life of the members.
The Oratorium has published many books, on subjects including the daily offices and gregorian chant.
