It would seem to me just as the temple had become horribly corrupted during the first coming of Jesus, the same will be said for the Church prior his second coming. Or as the apostle Paul called it, it will be in a state of Apostasy. As for those who have been mislead by the leaders they were taught to trust, it is up to them to read their entire Bible and find the Truth for themselves. For His people have always perished by the lack of knowledge.
