Sermon for the Feast of St. Thomas
“My Lord, and my God”
The Apostolic Saints are part of the Advent and none more so than Thomas, “called Didymus,” whom we more commonly call ‘Doubting Thomas.’ In the darkest time of nature’s year, there is another form of darkness that deepens nature’s darkness into something even more strange and fearful. The darkness of doubt leads to despair, the death of souls and communities, of cultures and churches.
Thomas’ feast day falls always within the season of Advent. He is the advent saint par excellence not just because his day of commemoration falls always within Advent and so close to the winter solstice and to Christ’s holy birth, the birth of God’s Son into our world of darkness, but because his doubting leads not to the darkness of despair and death but to the light of faith and hope. The doubting of Thomas provides for “the greater confirmation of our faith,” as another Thomas, Thomas Aquinas, reminds us.
The propers for his feast-day illumine the radical nature of Christ’s Incarnation. Ephesians reminds us of the fellowship of faith, that we are “fellow-citizens with the saints,” that we are “of the household of God,” “an holy temple in the Lord,” “an habitation of God through the Spirit,” and that Jesus Christ himself is “the chief corner-stone,” the structural and animating principle upon which all these images of indwelling depend.
