This edict pledged the State not to molest Christians so long as they did not attack the State religion. Thus began a series of com- promises, none of which gave any sure foothold. Two years later Constantine and Licinius gave the Christians "liberam atque absolutam colendae religionis libertatem" in the Edict of Milan, and conciliated both parties by defining ^'Divinitas in Sede Coelesti" as the object of State worship.
