Monastic Beginnings and Consecration
Niphon entered the Kiev Caves Monastery, where, according to the synaxarion, he struggled in asceticism through fasting, vigil, and prayer. He was chosen as Bishop of Novgorod to succeed Bishop John, who had retired to a monastery after twenty-five years of episcopal service.
He was consecrated bishop in Kiev by Metropolitan Michael and other hierarchs; Russian historical sources place the consecration in 1130. As bishop he sought to strengthen his flock in the Orthodox faith and to keep them from becoming separated from the Church.
