The Synaxis of the Seventy Apostles was established by the Orthodox Church to indicate the equal honor of each of the Seventy. They were sent two by two by the Lord Jesus Christ to go before Him into the cities He would visit (Luke 10:1).
Besides the celebration of the Synaxis of the Holy Disciples, the Church celebrates the memory of each of them during the course of the year:
St. James the Brother of the Lord (October 23); Mark the Evangelist (April 25); Luke the Evangelist (October 18); Cleopas (October 30), brother of St. Joseph the Betrothed, and Simeon his son (April 27); Barnabas (June 11); Joses, or Joseph, named Barsabas or Justus (October 30); Thaddeus (August 21); Ananias (October 1); Protomartyr Stephen the Archdeacon (December 27); Philip the Deacon (October 11); Prochorus the Deacon (28 July); Nicanor the Deacon (July 28 and December 28); Timon the Deacon (July 28 and December 30); Parmenas the Deacon (July 28); Timothy (January 22); Titus (August 25); Philemon (November 22 and February 19); Onesimus (February 15); Epaphras and Archippus (November 22 and February 19); Silas, Silvanus, Crescens or Criscus (July 30); Crispus and Epaenetos (July 30); Andronicus (May 17 and July 30); Stachys, Amplias, Urban, Narcissus, Apelles (October 31); Aristobulus (October 31 and March 16); Herodion or Rodion (April 8 and November 10); Agabus, Rufus, Asyncritus, Phlegon (April 8); Hermas (November 5, November 30 and May 31); Patrobas (November 5); Hermes (April 8); Linus, Gaius, Philologus (November 5); Lucius (September 10); Jason (April 28); Sosipater (April 28 and November 10); Olympas or Olympanus (November 10 ); Tertius (October 30 and November 10); Erastos (November 30), Quartus (November 10); Euodius (September 7); Onesiphorus (September 7 and December 8); Clement (November 25); Sosthenes (December 8); Apollos (March 30 and December 8); Tychicus, Epaphroditus (December 8); Carpus (May 26); Quadratus (September 21); Mark (September 27), called John, Zeno (September 27); Aristarchus (April 15 and September 27); Pudens and Trophimus (April 15); Mark nephew of Barnabas, Artemas (October 30); Aquila (July 14); Fortunatus (June 15) and Achaicus (January 4).
With the Descent of the Holy Spirit the Seventy Apostles preached in various lands. Some accompanied the Twelve Apostles, like the holy Evangelists Mark and Luke, or St. Paul’s companion Timothy, or Prochorus, the disciple of the holy Evangelist John the Theologian, and others. Many of them were thrown into prison for Christ, and many received the crown of martyrdom.
There are two more Apostles of the Seventy: St. Cephas, to whom the Lord appeared after the Resurrection (1 Cor. 15:5-6), and Simeon, called Niger (Acts 13:1). They also were glorified by apostolic preaching.
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.
The Church in particular venerates and praises the Seventy Apostles because they taught us to honor the Trinity One in Essence and Undivided.
In the ninth century St. Joseph the Hymnographer composed the Canon for the Synaxis of the Seventy Apostles of Christ.
From: OCA.org
In the longer Life of the Seventy Apostles by St. Dimitry of Rostov, we have more information on these early preachers of our Christian faith:
I. Saint James, Brother of the Lord (Commemorated October 23)
The holy Apostle Paul refers to James in the Epistle to the Galatians, saying, I went up to Jerusalem to see Peter, but other of the apostles saw I none, save James the Lord’s brother. Saint James was appointed Bishop of Jerusalem by the Lord Himself. The Jews hurled him from the pinnacle of the Temple for preaching Christ. He was injured, but not killed, when he struck the pavement below, so one of the Pharisees shattered his skull with a club, finishing him.
II. Saint Mark the Evangelist (April 25)
Mark wrote his Gospel under the direction of Saint Peter and is mentioned by that Apostle in his First General Epistle. Peter writes, The church that is at Babylon saluteth you; and so doth Mark my son. Peter ordained Mark Bishop of Alexandria. The idolaters of that city bound him, dragged him over jagged rocks, and beat him; whereupon, the Lord appeared, summoned him to heavenly glory, and received his spirit.
III. Saint Luke the Evangelist (October 18)
Luke wrote his Gospel under the guidance of the holy Apostle Paul, who mentions him in the Epistle to the Colossians, saying, Luke, the beloved physician, and Demas, greet you. Saint Luke also wrote the Acts of the Apostles. After toiling greatly in Christ’s service, Luke completed his labors in Thebes, a city of Boetia, where he was martyred.
IV. Saint Cleopas, Younger Brother of Joseph the Betrothed (October 30)
In his Gospel, Saint Luke writes that Cleopas was one of the two disciples to whom the Lord appeared on the road to Emmaus after His Resurrection. Luke was the other, although he does not mention his own name. Cleopas was subsequently slain by the Jews for preaching Christ, the murder taking place in the very house where the risen Lord was known by him in the breaking of bread.
V. Saint Symeon, Kinsman of the Lord (September 17 and April 27)
Saint Symeon was the second Bishop of Jerusalem, James’ successor. He was crucified for the crucified Christ.

According to the fourth chapter of the Book of Acts, this saint was surnamed Barnabas by the apostles. He is also mentioned in the second chapter of the Epistle to the Galatians, wherein Saint Paul writes, I went up to Jerusalem with Barnabas. Laboring in the ministry of the word, he was first (with Saint Paul) to preach Christ in Rome. He became Bishop of Milan and met his end on Cyprus, his homeland, being stoned by Greeks and Jews. Saint Barnabas was buried with a copy of Saint Matthew’s Gospel which he had written with his own hand.
VII. Saint Joses or Joseph, Also Called Barsabas and Justus (October 30)
Joses was one of the two candidates chosen as possible replacements for the fallen Judas (the other was Matthias). Saint Paul refers to him in the Epistle to the Colossians as Jesus, which is called Justus. The teachers of the Church say that Joses was a son of Joseph the Betrothed, like James, Simon, and Judas (not Iscariot). He became Bishop of Eleutheropolis and died a martyr.
VIII. Saint Thaddaeus (August 21)
Thaddaeus was first a disciple of Saint John the Forerunner, then of Christ. He is not to be confused with the holy Apostle Jude or Judas Thaddaeus, also known as Lebbaeus. Thaddaeus baptized Abgar, Prince of Edessa, and cleansed him of leprosy. After laboring much in proclaiming the gospel of Christ, he reposed in the Lord in the Phoenician city of Beirut.
IX. Saint Ananias (October 1)

Epaphras was Bishop of Colossae and also of the churches of Laodicea and Hierapolis. He shared Paul’s captivity in Rome, whence the great Apostle wrote the Colossians, Epaphras, who is one of you, a servant of Christ, saluteth you, always labouring fervently for you in prayers, that ye may stand perfect and complete in all the will of God. For I bear him record, that he hath a great zeal of you, and them that are in Laodicea, and them in Hierapolis.
XXI. Saint Archippus (November 22 and February 19)
Archippus, like Onesimus and Epaphras, is mentioned in the Epistle to Philemon. While Saint Epaphras was being held at Rome in fetters, Archippus succeeded him as Bishop of Colossae. Archippus was tending the flock of Christ in that city when Saint Paul wrote him this reminder: Take heed to the ministry which thou hast received in the Lord, that thou fulfil it.
XXII. Saint Silas (July 30)
With Saint Paul, the holy Silas preached the word of God, was flogged, and imprisoned. The Acts of the Apostles relates that Paul chose Silas and departed, confirming the churches. Silas became Bishop of Corinth and greatly labored proclaiming the gospel. After working numerous miracles, he departed to the Lord.
Silvanus transcribed Saint Peter’s First General Epistle, as the chief Apostle states: By Silvanus, a faithful brother, I have written. In his Second Epistle to the Corinthians, Saint Paul testifies that Silvanus assisted him in teaching the word of God. The Son of God, Jesus Christ, he says, was preached among you by us, even by me and Silvanus. As Bishop of Thessalonica, Silvanus suffered much for the faith, then departed to Christ, the Ruler of the contest.
