Editing Second Council of the Lateran (section)

==Tenth Ecumenical Council==
After the death of Honorius II, Petrus Leonis, under the name of [[Anacletus II]], was elected as Pope by a majority of the cardinals and with the support of the people of Rome on the same day as a minority elected [[Pope Innocent II|Innocent II]]. In 1135, Innocent II held a [[Council of Pisa (1135)|council at Pisa]], which confirmed his authority and condemned Anacletus. Anacletus's death in 1138 helped largely to solve the tension between rival factions. Nevertheless, Innocent decided to call the Tenth Ecumenical Council.<ref name="ce">{{CathEncy|wstitle=Second Lateran Council (1139)}}</ref>

The council assembled at the [[Lateran Palace]] and nearly a thousand prelates attended. In his opening statement Innocent deposed those who had been ordained and instituted by Anacletus or any of his adherents. King [[Roger II of Sicily]] was excommunicated{{sfn|Houben|2002|p=70}} for maintaining what was thought to be a schismatic attitude.

The council also condemned the teachings of the Petrobrusians and the Henricians, the followers of [[Peter of Bruys]] and [[Henry of Lausanne]]. Finally, the council drew up measures for the amendment of ecclesiastical morals and discipline which the council fathers considered had grown lax. Many of the canons relating to these matters were mostly a restating of the decrees of the [[Council of Reims]] and the [[Council of Clermont (1130)|Council of Clermont]].<ref name="ce" />
