Saint Mark and Saint Luke stand as pillars of the Gospel tradition, portrayed with serene strength and spiritual insight. Mark presents the open Word, symbol of his bold testimony to Christ’s mission. Beside him, Luke holds a closed book adorned with a cross, evoking both his authorship and the enduring wisdom of his Gospel. Above them, an angel proclaims “Holy, Holy, Holy,” drawing the heart upward in reverence. Below, scenes of their earthly ministries to teaching, healing, and writing which invite reflection on the power of divine inspiration and the sacred labor of proclaiming truth.
