Is the church mentioned in Jesus' end-times teaching about the tribulation and Second Coming?
No. In Jesus' end-times teaching about the tribulation and Second Coming, there is no Church language—not a word. His words concern the nation of Israel, and the Church age was kept secret, not divulged in that discourse. Jesus knew, but it was hidden.
Les explains that in the end-times teaching, survivors of the tribulation will see the Son of Man coming in the clouds with power and great glory. He shall send His angels with a great sound of a trumpet, and they shall gather His elect from the four winds. Les points out that in this passage there is no Church language—not a word. Jesus knew all things, but the Church age was kept secret; He does not divulge the 1900 and some years when Israel is not involved. Everything He says regards the nation of Israel. Peter in Acts 2 is in perfect accord with the Jewish program and knows nothing else, as the Old Testament program from Psalms 2 is fulfilled in the coming of the Messiah.
