Mission at Rostov
According to tradition, near Abramius's dwelling stood a pagan temple containing a stone idol of Veles (Volos), which is said to have caused fright among the inhabitants of Rostov. The accounts relate that the Apostle John the Theologian appeared to Abramius and gave him a staff crowned with a cross, with which he destroyed the idol.
On the temple site Abramius founded a monastery in honor of the Theophany and became its head. To commemorate the vision he also built a church dedicated to Saint John the Theologian. His preaching is credited with converting many of the local pagans to Christianity. The monastery received all who came to it, and Abramius himself is remembered for humble manual labor in its service.
