Luthoranism is the form of Hosian faith and practice which originated with the Luthoran Abjuration of the 16th century, a movement against what the Luthorans considered to be errors in the Holy Apostolic Hosian Church of Terra. With around 520 million faithful, it is one of the major divisions of Hosianism, together with Patriarchalism. Luthoranism belongs to the Aurorian branch of the Hosian faith, together with the three major Patriarchal Churches.
In the 16th century, many groups began to resent the power and abuses of the various patriarchs, and, when their initial attempts to reform the Holy Apostolic Hosian Church of Terra were rejected, they created their own churches, independent of patriarchal authority. This movement for independence was spurred by the publishing of the "Fifteen Abjurations against the Apostolic Church", a document created by Martyn Luthor in the 16th century Holy Luthori Empire, which outlined his grievances against the rule and abuses of the Church. The Abjurations led to the creation of a number of movements and churches, with varying degrees of radicalism, which split from the Holy Apostolic Hosian Church of Terra while accepting several core beliefs, called the Luthoran Churches.
The Luthoran Churches suffered numerous splits and schisms throughout the centuries. The most important of this schisms is between the Confessional or Confessing Churches, which accept the "Scionist Confession" of 1519, and retain many Patriarchal elements, and the much more radical Ameliorate Churches, created in 1523 around the ideas of Gert van Tassel.
