Joel as if ties time up in a knot: He speaks of the coming judgment over sinners and the salvation of those who believe in God. The beginning and end of Church history are connected. This is a common example of a multi-layered prophetic utterance.
The Law was given on the day of the Jewish Pentecost, and in order to fulfill the essence of the Law spiritually, in a Christian manner, the grace of the Holy Spirit was necessary.
The Church, in fact, continues the path of Christ on Earth.
Christ already glorified human nature by His Resurrection. What’s particular about the Ascension in the history of our salvation?
Christ did and taught, and that’s what the Church should do. And the Church is us.
