Vision to the Youth Bartholomew by Mikhail Nesterov (1862–1942). Baptized ‘Bartholomew’, Sergius of Radonezh (how he is most commonly referred to in the East) took the name ‘Sergius’ when he first took his monastic vows. From Wikimedia.
¶ Or this:
Almighty God, who in days of trouble and rebuke didst raise up blessed Sergius to be a defender of thy people: Strengthen and confirm our brethren of the Russian Church, that holding fast the faith once for all delivered to the saints, they may worship thee and serve thee all the days of their life; through Jesus Christ our Lord. Amen.
