Three Great Woes of Catholic History, of Apocalypse: Protestantism, Enlightenment, and Godless Apostasy
Ascension thursday, the 5th apocalyptic day
It is likely that the reason that Christ ascended into heaven on thursday, which is the fifth day apocalyptically, is that according to sacred tradition, especially Saint Augustine and then Saint Methodius of Olympus, five are the ages of the old law, and the sixth day inaugurates the church.
In this theology, the first coming of Christ is what concludes these first five ages, even as in Advent there are four lesser masses and the fifth mass is Christmas.
This makes sense because after Christ's first coming, which ended effectively with the ascension, the redemption of the world would never again involve a direct divine revelatory presence within human history, because from thenceforth, salvation will be mediated through the church in her sacraments and infallible proclamation of the truths of Christ through apostolic succession.
And this is then the 6th great age of human history, although it seems that with the minor Godless age of atheism and relativism in the 20th century down to our own day, we are no longer in the 6th apocalyptic age but in the seventh, or the sunset the darkness of the seventh day, but when the chastisement comes the Sun will start to rise because the world will begin to see the light of the error of their ways, and finally , when they convert ,there will be the glory of the light of our lady's age of peace, the seventh day Sabbath!
