I'm sure the author is aware that those Patristic references to the Rapture place it within the events of the Second Coming.
Not only are there many references in early church writings, but the pre-trib notion is also found early on in church History,
Oh, really? What early church references and writings mention a pre-trib rapture?
Historical claims require historical proof. I suspect you're going to be shown wanting on this point.
Paul and Jesus were the first to reveal the mystery of the Rapture to end the Age of the Ekklesia. The Church/Ekklesia will not be in the testing period known as the seventieth week of Daniel, the Time of Jacob's Trouble, The Tribulation, the hour of testing. John later wrote what he was shown regarding these events. So there are three to start with.
And, btw, why would you want to start an exchange with a closed mind, such as 'I suspect you're going to be shown wanting on this point.' If you need to win something your ego desires, I will bow out now and leave you to your 'victory'.
I'll check back in late this evening or tomorrow morning, when I get back in town. Have a wonderful day ...
