Continuing through the Catechism of the Catholic Church as it relates to prophecy:
726 At the end of this mission of the Spirit, Mary became the Woman, the new Eve (“mother of the living”), the mother of the “whole Christ.” As such, she was present with the Twelve, who “with one accord devoted themselves to prayer,” at the dawn of the “end time” which the Spirit was to inaugurate on the morning of Pentecost with the manifestation of the Church.
The Catechism reaffirms the concept of the “end time” having been initiated at Pentecost, which we see as the initiation of the Church, of which Mary was also an integral part of events (Aside from having been the chosen vessel for carrying God). Too often, the “end times” discussion boils down to the perceptions of those who read prophetic events in light of the final period immediately preceding the return of Christ, whether that be a seven year tribulation period, or a 3 and a half year great tribulation, or the idea of a rapture of Christians that initiates a world gone to hell in a hand-basket for everyone else. In reality, everyone who has lived since Pentecost until now has been part of “end time” events. Yes, there will be a final culmination in which things are magnified and condensed into a small period of time, but that is really a microcosm of everything that has occurred throughout Christian history. From the earliest Roman persecutions to the countless other individual martyrdoms, religious wars, atheistic assaults on Christendom (in general and in general nationalistic terms), the trials and tribulations we read about in the book of Revelation and other end-time allusions in Scripture are ever evident.
