Lateran Council

Roman Catholicism

Quick Summary

The Lateran Councils were significant ecumenical councils held in the Lateran Palace in Rome, primarily within the Roman Catholic Church. These councils addressed various theological and disciplinary matters throughout the medieval period and into the Renaissance.

The First Lateran Council (1123) reiterated earlier decrees, condemned simony, and forbade marriage for clerics in major orders. The Second Lateran Council (1139) condemned followers of Arnold of Brescia and addressed issues concerning marriage and sacraments. The Third Lateran Council (1179) established rules for papal elections and condemned the Cathari. The Fourth Lateran Council (1215) is considered highly influential, defining transubstantiation and mandating annual confession and communion during Lent. The Fifth Lateran Council (1512–17) addressed church reform and affirmed the immortality of the soul.12345

It is important to note that the Orthodox churches do not recognize any of these five Lateran councils as ecumenical.2453
