The name of Saint Crispus is found in Acts18:8 and 1 Cor. 1:14. He was the chief ruler of the synagogue at Corinth, and was baptized by St Paul. He became the bishop of the Greek island of Aegina.
There are discrepancies and errors in some lists of the Seventy Apostles. In a list attributed to St Dorotheus of Tyre (June 5) some names are repeated (Rodion, or Herodion, Apollos, Tychicus, Aristarchus), while others are omitted (Timothy, Titus, Epaphras, Archippus, Aquila, Olympas). St Demetrius of Rostov consulted the Holy Scripture, the traditions passed down by the Fathers, and the accounts of trustworthy historians when he attempted to correct the mistakes and uncertainties in the list in compiling his collection of Lives of the Saints.
St Crispus appears on the list of St Dorotheus, but other lists say he is the same person as St Crescens. He does not appear to have a separate commemoration.
