Isaiah

Isaiah is often called the Fifth Evangelist because his prophecies describe the coming Messiah with such striking clarity that they read almost like eyewitness accounts written seven centuries before Christ. His ministry spanned the reigns of four kings of Judah, during a period of political upheaval when Assyria threatened to swallow the tiny kingdom whole.

Isaiah's call is one of the most memorable in Scripture: a vision of God enthroned in the Temple, surrounded by seraphim crying Holy, Holy, Holy. Overwhelmed by his own unworthiness, Isaiah cried out, Woe is me! I am a man of unclean lips. A seraph touched his mouth with a burning coal, purifying him, and God asked, Whom shall I send? Isaiah's response — Here I am, send me — has echoed through the centuries as the model of prophetic vocation.

His messianic prophecies are woven into the fabric of Catholic worship. The suffering servant passages of Isaiah 53 — He was pierced for our transgressions, crushed for our iniquities — form the heart of the Good Friday liturgy. His vision of a virgin conceiving and bearing a son named Emmanuel is proclaimed every Advent. Isaiah reminds us that God's plan unfolds across centuries and that faithfulness requires trusting in promises we may not live to see fulfilled.
