Saint Nicodemus was a prominent Pharisee who believed in Christ. The Savior explained to him how man is regenerated through Baptism, but he did not understand how a man could be born again. When the Lord reproved him for his ignorance, he accepted it with humility (John 3:1-21).

Nicodemus came back to Christ from time to time, defended Him to the Pharisees (John 7:50-52), and brought spices to anoint His body (John 19:39). After being cast out of the synagogue for his belief in Christ, Saint Nicodemus went to live with Saint Gamaliel at his country house, remaining there until his death.

The relics of Saints Stephen, Gamaliel, Abibas, and Nicodemus were transferred from Jerusalem to Constantinople in 428 and placed in the church of the holy deacon Laurence (August 10).
