Bible Translators Theologians Gnesio-Lutherans (from Greek γνήσιος [gnesios]: genuine, authentic)[1] is a modern name for a theological party in the Lutheran churches,[2] in opposition to the Philippists[3] after the death of Martin Luther and before the Formula of Concord.
Later Flacian became to mean an adherent of Matthias Flacius' view of original sin, rejected by the Formula of Concord.
After the death of Martin Luther, several theological controversies arose among Lutherans due mostly to the teachings of Philip Melanchthon.
The Gnesio-Lutherans exercised strict doctrinal discipline, but they also opposed with equal determination what they considered to be the errors of their fellow combatants like von Amsdorf (Amsdorfians), Flacius (Flacians), Andreas Poach, and others.
Unlike the Gnesio-Lutherans, members of the centre party were opposed to any unnecessary controversies involving no doctrinal differences, and careful not to fall into any extreme position themselves.
