Timotheus of Constantinopolis

Timothy of Constantinople (Greek: Τιμόθεος; fl. c. 600/700) was a Chalcedonian Christian heresiologist and presbyter of the church of Hagia Sophia in Constantinople. He wrote a treatise in Greek on Christian heresies from a Chalcedonian perspective, On Those Who Enter the Church, or On the Reception of Heretics. This pastoral work is best described as "a handbook on the procedure for admitting heretics to the church".

Timothy classifies heresies based on the requirements for admission that the orthodox church placed on their members. In his first category were those heretics who would need to be baptised before they could be accepted into the church; in the second, those who needed to be anointed but not baptised; and in the third, those who only needed to abjure all heresy (including their own former beliefs) by pronouncing an anathema. The same three categories were used by Theodore the Studite writing one or two centuries later. Theodore the Studite, taking a more practical stance, lists only the Manichaeans, Tascodrugites and Marcionites in his first class.

Timothy's third class includes the major anti-Chalcedonian sects of Nestorians and Miaphysites, a collection of sects he calls Marcianists and also the Melitians, who he says commit no error but schism. Timothy gives two slightly different lists of the miaphysite sects. The first is a list of sixteen groups Timothy labels theopaschite and the second is a list of "the schismatics called diacrinomenoi", which contains twelve groups. Together the two lists name the Eutychians, including the Dioscorians and Petrites; Acephali, who are subdivided into three sects; Julianists, who are subdivided into three sects; and Severans or Theodosians, who are subdivided into eight factions (Agnoetae, Condobaudites, Niobites, two groups of Tritheists (These were the Philoponians and the Cononites.) He recognized Jacob of Serugh as orthodox.

Several sects mentioned by Timothy, such as the Melchisedechites, he describes as having Jewish practices, including sabbatarianism, celebration of new moons and delaying baptism.
