Louis the Pious

From Conservapedia

When Charlemagne died in 814 his son Louis the Pious became Holy Roman Emperor. During his reign, he sought to continue reform of the monasteries by appointing Benedict of Aniane (750-821) as his adviser on church affairs. Some of the great theological disputes began to rear their heads, including the controversy over predestination stirred up by Gottschalk of Orbais (805-869) amongst others, and the dispute between Paschasius Radbertus (785-860) and Ratramnus of Corbie (died 868) over whether the bread and wine of the Lord’s Supper were miraculously converted into the flesh and blood of Christ.
