In the Traditional calendar we are now in Epiphanytide. We continue to reflect on this Mystery of light, the manifestation of Christ to the nations. The importance of this Feast theologically and liturgically cannot be overstated. St Peter Chrysologus observed: In the mystery of our Lord’s Incarnation there were clear indications of his eternal Godhead. Yet the great events we celebrate today disclose and reveal in different ways the fact that God himself took a human body. Mortal man, enshrouded always in darkness, must not
be left in ignorance, and so be deprived of what he can understand and retain only by grace (Sermon 160 PL 52, 620-622).
This mystery and all mysteries need to be celebrated in all their splendour and import, lest we be left in ignorance, and so be deprived of what [we] can understand and retain only by grace. In the Church, this instruction is generally speaking accessible in the sermon or homily; and the grace to retain what we have learned is obtained through the celebration of the Sacraments and our willingness to be formed by the doctrine of the faith.
