Today, December 27, is the feast day of St. John the Evangelist. While internal evidence in the Bible suggests otherwise, tradition identifies him as the son of Zebedee, the disciple whom Jesus loved, and the author of all five books in the New Testament ascribed to a John. As such his role in the New Testament is rivaled only by Peter and Paul. He is recognized in Christian art by usually being beardless or symbolized by an eagle or a chalice with a snake.

Co-editing the works of the pioneering church historian Philip Schaff with my colleague Ted Trost, I learned much about the adulation John has received through the centuries. Schaff was born almost 200 years ago on January 1, 1819. Next week the bicentennial of his birth will be celebrated at the annual meeting of the American Society of Church History, which he founded.

In his first book, The Principle of Protestantism (1845), Schaff wrote

John, the apostle of love, has not without reason been styled by the church the “Theologian” per eminentiam. For by the eagle flight of his believing speculation into the depths of God and his Word as existing before the world and then made flesh for our salvation, he may be said to have led the way to Christian theology in its bold and glorious course. His love is only the strong will-force of knowledge, his knowledge but the keen vision of love.

The whole history of the Church furnishes proof that the men who have exerted the greatest and most happy influence, the wakers of a new life, the pillars of the temple of God, have always been distinguished also above there contemporaries by a thorough scientific cultivation.

Schaff cites a medieval Latin hymn in praise of John. In his St. John the Divine: The Deified Evangelist in Medieval Art and Theology, Jeffery Hamburger translates it:

He flies like a bird without limit,
in that neither seer nor prophet
ever flew higher.
As much what would be fulfilled as what has been,
never were so many secrets seen
so purely by a pure man.

Cited in Development of the Church, 175

Schaff was an ecumenist, passionately concerned with the reunion of what he, following his German teachers, called the church of Peter (Roman Catholicism) with the church of Paul (Protestantism) in the coming church of John. He closes the Principle of Protestantism stating

The revivification of the spirit of John the evangelist, in the Church, will open the way directly for his second coming, to establish the Church absolute and triumphant, in which law and freedom shall both be perfect in one, and the results of all previous development appear conserved as the constituent elements of a higher and more
glorious state. To this refers the mystical sense of Christ’s word, John 21:22, where he speaks enigmatically of John’s tarrying till his second coming.

With such an emphasis on John–the beloved disciple, the theologian, the evangelist, the author of Revelation–as the embodiment of the coming church of the future, it is unsurprising that Americans would name him patron of their largest and most ambitious church, the Cathedral of St. John the Divine in New York. Its name was fixed in a 1873 charter when Schaff was in his prime at age 54. Its cornerstone was laid on this day in 1892 a year before Schaff’s death. Its structure, like the reunion of Christ’s visible church is still unfinished.

While for Schaff, the key attributes of John were knowledge and love, the traditional Anglican collect for this feast highlights the theme of the light of truth appropriate for this dark time of year in the northern hemisphere. The phrasing in the Church of England’s Common Worship captures it best.

Merciful Lord,
cast your bright beams of light upon the Church:
that, being enlightened by the teaching of your most blessed apostle and evangelist Saint John,
we may so walk in the light of your truth
that we may at last attain to the light of everlasting life;
through Jesus Christ our Lord.
