Most Catholic scholars recognize that the genre of this book and interpret it accordingly…i.e. it was not meant to predict the future but rather was written to offer hope and teaching to those in the contemporary situation (presumably, late first century A.D.).
Various Fathers, Doctors, and Saints of the Church, who expressed a position on the question, held that the Apocalypse (the Book of Revelation) describes the future tribulation.
Jesus taught that the Book of Daniel described the future tribulation:
[Matthew]
{24:14} And this Gospel of the kingdom shall be preached throughout the entire world, as a testimony to all nations. And then the consummation will occur.
{24:15} Therefore, when you will have seen the abomination of desolation, which was spoken of by the prophet Daniel, standing in the holy place, may he who reads understand,
{24:16} then those who are in Judea, let them flee to the mountains.
{24:17} And whoever is on the roof, let him not descend to take anything from his house.
{24:18} And whoever is in the field, let him not turn back to take his tunic.
{24:19} So then, woe to those who are pregnant or nursing in those days.
{24:20} But pray that your flight may not be in winter, or on the Sabbath.
{24:21} For then there will be a great tribulation, such as has not been from the beginning of the world until the present, and such as will not be.
But modernist scholars have explained away all the passage of the OT and NT referring to the tribulation.
