The paper discusses the Christological bearing of certain Byzantine festal hymns, whose roots stretch back to the early Christian tradition, but which are still used in the services of the Orthodox Church. These hymns avoid the vocabulary of their contemporary dogmatic debates, and offer an alternative poetic theology deeplyrooted in Biblical imagery, yet surprisingly precise and effective in conveying the very same message about Christ. This finding opens up the discussion of theological method, namely the question of how these hymns (...) could be taken into account as direct sources for theology, on a par with the data provided by the ecumenical councils, and the subsequent patristic and medieval theology.
