Luke of Constantinople

[2] In the end, a synod held at Constantinople in 1157 adopted a compromise formula, that the Word made flesh offered a double sacrifice to the Holy Trinity, despite the dissidence of Patriarch of Antioch-elect Soterichus Panteugenus.

Chrysoberges, at the behest of the Emperor Manuel I Komnenos, convened several meetings of the synod in 1166 to solve the problem, which condemned as heretical the explanations of Demetrius and the laity that followed him.

[4] Other heresies continued to flourish in Byzantine possessions in Europe, including Bogomils, Paulicians, and Monophysites which Luke and his successors had difficulty in suppressing.

Some have taken on posts as curators or overseers of aristocratic houses and estates; others have undertaken the collection of public taxes... others have accepted dignities and magistracies assigned to the civil establishment... we enjoin such people to desist from now on from all the aforesaid occupations, and to devote themselves to ecclesiastical exigencies..."[6] Such a separation of church and state was key to preserve the church from undue secular influence over matters it considered strictly clerical.

This was especially key at the time as the rule of the Emperor Manuel I Komnenos was noted for its autocratic style and caesaropapism, and though idiosyncratic, generally made the patriarchate subservient directly to the needs of the state.
