The New Testament tells us that during the period between the Ascension and Pentecost “all … joined in continuous prayer, together with several women, including Mary the mother of Jesus, and with his brothers” (Acts 1:14) while they awaited being “clothed with the power from on high” (Lk 24:49). The pious exercise of the Pentecost novena, widely practiced among the faithful, emerged from prayerful reflection on this salvific event. Indeed, this novena is already present in the Missal and in the Liturgy of the Hours, especially in the second vespers of Pentecost: the biblical and eucological texts, in different ways, recall the disciples’ expectation of the Paraclete.
