The Revd Antonio Garcia Fuente
The Liturgy today gives us two readings where the Holy Spirit descends over the Apostles, the first one from Acts (2:1-21), the second one from the Gospel of John (20:19-23). They are two different events that strongly relate to each other.
The first one, from the book of Acts, happens during the feast of Pentecost. First century Jews, such as the Apostles, would not have missed an all important detail about this date: Pentecost. If Easter is the feast that celebrates the epic event when Israel crosses the Red Sea being freed from Pharaoh (cf. Ex 14), Pentecost is the feast that celebrates the moment in which God gives the law to Moses in the Mount of Sinai (cf. Ex 19ff), the law of the old covenant. Pentecost was the day in which the Apostles received the fullness of the new law, the new covenant.
