Well 'rapture' or 'harpazo' IS in the Bible. We 'fundies' got that rapture word from y'alls Latin Bible:
deinde nos qui vivimus qui relinquimur simul rapiemur cum illis in nubibus obviam Domino in aera et sic semper cum Domino erimus(1 Thes. 4:17)
So established it is there. And the passage does address being with the Lord during this event; and meeting Christ in the clouds. Am I 'dogmatic' about 'when' this occurs...No. From my research nor is the Catholic church. So if you have an infallible read on this let us know.
Irenaeus did opine on the matter briefly:
In the previous books I have set forth the causes for which God permitted these things to be made, and have pointed out that all such have been created for the benefit of that human nature which is saved, ripening for immortality that which is [possessed] of its own free will and its own power, and preparing and rendering it more adapted for eternal subjection to God. And therefore the creation is suited to [the wants of] man; for man was not made for its sake, but creation for the sake of man. Those nations however, who did not of themselves raise up their eyes unto heaven, nor returned thanks to their Maker, nor wished to behold the light of truth, but who were like blind mice concealed in the depths of ignorance, the word justly reckons “as waste water from a sink, and as the turning-weight of a balance— in fact, as nothing;” Isaiah 40:15 so far useful and serviceable to the just, as stubble conduces towards the growth of the wheat, and its straw, by means of combustion, serves for working gold. And therefore, when in the end the Church shall be suddenly caught up from this, it is said, “There shall be tribulation such as has not been since the beginning, neither shall be.” Matthew 24:21 For this is the last contest of the righteous, in which, when they overcome they are crowned with incorruption.

Take whatever you like out of context, weave whatever mess you want out of it, but there ain't no Rapture coming to save Christians from the turmoil.
That trash is exactly the same sort of lie as, "No, you shall not die the death.", something to encourage the sap listening to go their own way rather than following Christ.
