At Easter, the κόσμος bows to the Majesty of Christ the King and High Priest, per quem omnia facta sunt. On Pentecost, creation renders homage to the Creator Spirit, to the Creator Spiritus who in his power renews the face of the earth. At Easter, the Messianic promises of the Ancient Law are fulfilled. On Pentecost, the promises of the Messiah himself are realized in His Mystical Body, the Holy Church, the Mother of Saints – Madre de’ Santi – as Manzoni calls her in his famous sacred hymn for this feast.
