A "pre-tribulation rapture of the church" is a novel doctrine that has only been introduced in recent history. The orthodox doctrine has always been that the church will endure tribulation in the world.
"I have said these things to you, that in me you may have peace. In the world you will have tribulation. But take heart; I have overcome the world."
- John 16:33
There is always value in studying and seeking a better understanding of scripture:
"Be diligent to present yourself approved to God as a workman who does not need to be ashamed, accurately handling the word of truth."
- 2 Timothy 2:15
