Becker as an expansion of German theologian Ernst Troeltsch's church–sect typology.Troeltsch's aim was to distinguish between three main types of religious behavior: churchly, sectarian and mystical.Lofland published his findings in 1964 as a doctoral thesis entitled: "The World Savers: A Field Study of Cult Processes", and in 1966 in book form by Prentice-Hall as Doomsday Cult: A Study of Conversion, Proselytization and Maintenance of Faith.
In 1999, Eileen Barker estimated that NRMs, of which some but not all have been labelled as cults, number in the tens of thousands worldwide, most of which originated in Asia or Africa; and that the great majority of which have only a few members, some have thousands and only very few have more than a million.
Becker created four categories out of Troeltsch's first two by splitting church into "ecclesia" and "denomination", and sect into "sect" and "cult".
Later sociological formulations built on these characteristics, placing an additional emphasis on cults as deviant religious groups "deriving their inspiration from outside of the predominant religious culture".
References to the "cult" of, for example, a particular Catholic saint, or the imperial cult of ancient Rome, use this sense of the word.
Beginning in the 1930s, cults became the object of sociological study in the context of the study of religious behavior.
Many, but not all of them, have been considered to be cults.
