In Christianity, "saint" has a wide variety of meanings, depending on the context and denomination. The original Christian denotation was any believer who is "in Christ" and in whom Christ dwells, whether in Heaven or on earth. In Orthodox and Roman Catholic doctrine, all of their faithful deceased in Heaven are considered to be saints, but some are considered worthy of greater honor, emulation, or veneration, with official ecclesiastical recognition given to some saints by canonization or glorification.

Mary (Miriam: Hebrew: מרים‎; c. 15 BC – c. 48 AD), also known as Saint Mary or the Blessed Virgin Mary, or Παναγία in Greek, is identified in the Bible and Quran as the mother of Jesus. Christians hold her son Jesus to be the Christ or Messiah foretold in Jewish scripture, and the God made flesh; Muslims also believe in Jesus as the foretold messiah, but disavow any actual divinity, instead regarding him as one of God's greatest Messengers.
