Pope Liberius also noticed his abilities and sent him on a mission to the Emperor Constantius to try to resolve the troubles between Arians and Catholics. Seeming to agree, Constantius convened a council in Milan in 355. The powerful Arians however weren't there to talk but to force their own will on the others. A horrified Eusebius watched as his worst fears were confirmed and the Arians made this peace council into a condemnation of Saint Athanasius, their chief opponent. Eusebius, unafraid of their power, slapped the Nicene Creed down on the table and demanded that everyone sign that before condemning Athanasius. The Nicene Creed, adopted by a council of the full Church, proclaims that Jesus is one in being with the Father -- directly contradicting the Arian teaching.
