Relationship of Salome and Mary
Saint Salome is venerated as a saint in the Catholic, Orthodox, Lutheran and the Anglican Churches.
The Catholic Church is somewhat unsure who St. Salome May truly be.
For some centuries, religious art throughout Germany and the Low Countries frequently presented Saint Anne with her husbands, daughters, sons-in-law and grandchildren as a group known as the Holy Kinship. During the Reformation the idea of the three husbands was rejected by Protestants, and by the Council of Trent by Catholic theologians also, but Salome continued to be regarded as probably the sister of the Virgin Mary, and the wife of Zebedee, and mother of the two apostles. The Catholic Encyclopedia of 1913 said (rather more cautiously than leading 19th-century Protestant books of biblical reference) that "some writers conjecture more or less plausibly that she is the sister of the Blessed Virgin mentioned in John 19:25".2
The Catholic Encyclopedia explains it as follow:
(1) The daughter of Herod Philip and Herodias (Matthew 14:6-8: Mark 6:22; cf. Josephus, "Antiq. Jud.", XVIII, 5:4), at whose request John the Baptist was beheaded.
(2) One of the holy women present at the Crucifixion, and who visited the tomb on the morning of the Resurrection (Mark 15:40; 16:1). In Mark 15:4, we read: "And there were also women looking on afar off: among whom was Mary Magdalen, and Mary the Mother of James the Less and of Joseph, and Salome." The parallel passage of Matthew reads thus: "Among whom was Mary Magdalen, and Mary the mother of James and Joseph, and the mother of the sons of Zebedee" (Matthew 27:56). Comparison of the two gives a well-grounded probability that the Salome of the former is identical with the mother of the sons of Zebedee in the latter, who is mentioned also in Matthew 20:20 sq., in connection with the petition in favour of her sons. Beyond these references in the Gospel narrative and what may be inferred from them nothing is known of Salome, though some writers conjecture more or less plausibly that she is the sister of the Blessed Virgin mentioned in John 19:25. - Salome
Salome was the wife of Zebedee and mother of Saint John the Apostle, and Saint James the Greater. May have been a cousin of the Blessed Virgin Mary. One of the “three Marys,” the holy women who ministered to Jesus during his earthly ministry, and may have accompanied him on his travels. Witnessed Christ’s death on the cross, his entombment, and his resurrection. Mark mentions Salome as one of the women who came to anoint the body of Jesus on the morning of the Resurrection.
As for the Orthodox Churches St. Salome was a daughter of righteous of a previous marriage of Joseph, the foster father of Our Lord.
In this case, we speak of Salome. Now, Salome was a daughter of righteous Joseph, St. Joseph, our Lord Jesus Christ’s foster father, and another woman named Salome. Out of this union there were a total of seven children that were produced. We had James and Joses and Jude and Symeon, and three daughters, Esther, Martha, and our Salome. Of course, out of this group, one of them, James, became an apostle of the 70 and first bishop of Jerusalem. Another one, Jude, became one of the inner circle, if you will, of the Lord, being one of his twelve disciples. When, of course, Joseph, who was a widower at that time, because he lost his wife Salome, brought home his betrothed, Mary, the Theotokos, well, Jude and James were probably still living at home.
Later on, Salome would marry a man named Zebedee, who is mentioned in the Scriptures, who was a fisherman, although he seems to disappear before the Lord’s passion, so we’re not sure exactly how long he lived or what happened to him. But we do know that from that illustrious pairing there came another James and John, and both of these would be known to the Church as the sons of thunder. So in effect, you had James the brother of the Lord who was the uncle of James the son of Zebedee and Salome.
Now the Lord also called these two right after he called Andrew and Simon Peter. He also saw them fishing, and they immediately gave up their nets and went to follow him. Salome, of course, was one of the myrrh-bearing women who was present at all of the critical times of the Lord’s life. They were certainly there at the foot of the cross; we know this. And Salome was also one to witness the resurrection. So her importance lies not, as it does in so many of the lives of the saints, in great exploits and miracles and all these sorts of things that many of our greatest saints do to get themselves under the watchful eye of the universal Church. Instead, she was one who was simply chosen. - Salome the Myrrhbearer
Some Protestant viewpoints of who St. Salome is more down to earth:
The Salome who is mentioned by name in Mark’s Gospel was one of many devoted female followers of Jesus. She was a witness of Jesus’s ministry and of his crucifixion. She seems to have been an independent woman (single, widowed, or divorced) and was one of the myrrh bearers who brought spices to anoint the body of her beloved Lord. This much we know. The fact that she appears in later works may be an indication that Salome was prominent among the first followers of Jesus. Certainly, she was prominent enough to be mentioned by name in Mark’s Gospel
Salome has been sainted and is commemorated in the Roman Catholic Church with feast days on April 24th and on October 22nd. The Eastern Orthodox Church commemorates Salome, Joanna, and Mary (the mother of James?) on August 3rd. The Eastern Orthodox Church commemorate the myrrh bearers on the second Sunday after Resurrection Sunday. The following is a hymn sung on the Sunday of the Myrrh-Bearing Women:
You did command the myrrh bearers to rejoice, O Christ!
By Your Resurrection, You did stop the lamentation of Eve, O God!
You did command Your apostles to preach: The Savior is Risen!
