Catechism Question #84 (July)
Q. What is meant by the words, "until he come," which are used by the apostle Paul in reference to the Lord's Supper?
A. They plainly teach us that our Lord Jesus Christ will come a second time; which is the joy and hope of all believers.
Acts 1:11 - "Men of Galilee, why do you stand gazing up into heaven? This same Jesus, who was taken up from you into heaven, will so come in like manner as you saw Him go into heaven."
