Is there any prophetic utterance connected with the church age?
No. For the most part, no prophetic utterance is connected with the church age. Scripture provides nothing to date Christ's return for the church; date-setters should be marked false. Only after the church age ends and the seven-year tribulation begins does prophecy and a time frame resume.
Les teaches that for the most part there is no prophetic utterance connected with the church age, and he says to always remember that. When people claim a specific day for the Lord's coming, they should be marked off as false from the start, because nothing in Scripture can help set a date for the return of Christ for the church. But once the church age is done and that undetermined period of time ends, the seven years of tribulation begin; then prophecy and a time frame resume, with seven years elapsing in prophecy. The church age itself has nothing like that.
