The Coptic Orthodox Church affirms Isaiah 7:14 as a prophecy of the Virgin Mary and birth of Christ. The Coptic tradition, rooted in the Septuagint (Greek OT), reads parthenos ('virgin') rather than Hebrew almah. This Greek rendering was Scripture of the early church and is authoritative in Orthodox tradition. The Coptic liturgical tradition strongly emphasizes Mary's perpetual virginity as essential to proper Christology: Mary is Theotokos (God-bearer), and her virginity is foundational to Orthodox soteriology and veneration. Isaiah 7:14 is understood as a clear messianic prophecy fulfilled in the Incarnation.
