Saint Euphrosinus of Sinózersk, in the world Ephraim, was born in Karelia near Lake Ladoga. In his youth, he lived at the Valaam Monastery, then moved to Veliky Novgorod. After a long stay in Novgorod, he went to the Bezhitskaya Pustyn, becoming a priest in the village of Dolosskoye. After his tonsure in the Assumption Tikhvin Monastery, in 1600 he began to live in solitude on the shores of Lake Sinichye, feeding on wild plants. Local residents began to visit him for guidance, and some stayed with him. In 1612, when Polish troops were plundering Russia, many sought refuge in his wilderness. The saint predicted the approach of the Poles and advised everyone to flee, but some did not believe him. He remained in the wilderness, saying that he had come to die for Christ.
On the next day, March 20, the Poles attacked the monastery. The saint came out in his schemamonk's attire and stood by the cross he had erected. The enemies demanded the monastery's possessions, to which he replied that all the wealth was in the church of the Most Holy Theotokos. The Poles, not understanding him, rushed to the temple, and one of them mortally wounded the saint. His body was buried with honor on March 28, along with the monk Jonah and all who perished by the sword. Thirty-four years after the saint's death, a new church was built in his monastery in the name of the Holy Trinity. By the blessing of Metropolitan Macarius of Novgorod, on March 25, 1655, the relics of the saint were transferred under the bell tower.
