Nowhere does it say in our faith that the events that lead up to the Second Coming have to happen all in one day or all in one year. And in fact, the Catechism of the Catholic Church says that the last days is the time of the Church (CCC 732). So, that means that from then until now we have been in the last days which means that the events of the End Times can be spread out over this whole time. In Matt. 24, the events are compared to birth-pangs. When a woman experiences these, they start out spread apart and then become more frequent and more intense as the time comes closer. I believe that the Crusades, for example, was one of the End Times events (see my thread about it
here). And I believe that the “Black Death” was another event of the End Times. I believe that these events have been adding up over time. An analogy is how sand passes through an hour glass and eventually gets full down at the bottom.
“But do not ignore this one fact, beloved, that with the Lord one day is as a thousand years, and a thousand years as one day.” - 2 Peter 3:8
Now consider the unprecedented things of our age such as so-called same-sex “marriage” laws and it suddenly being accepted by nation after nation. Another is so-called “abortion rights” going global. And no one 100 years ago or more had to worry about the world being destroyed by a nuclear war.
