Ephesians 1:20-22--"Which he wrought in Christ, when he raised him from the dead, (or, having raised him from the dead,) and set him at his own right hand in the heavenly places, far above all principality, and power, and might, and dominion, and every name that is named, not only in this world, but also in that which is to come: and hath put all things under his feet, and gave him to be head over all things to the church." Hebrews 2:8, 9--"But now we see not yet all things put under him (man;) but we see Jesus, who was made a little lower than the angels, for the suffering of death, crowned with glory and honor." Observe, that the Apostle's great object in this epistle is, to show that Christ is _in heaven_, forever interceding for the church. Now, is it not manifest from these texts, that Christ became the head of the corner when he ascended to his Father and our Father, to his God and our God? Nor is there any thing in Acts 4:10, 11, that contradicts this idea. Brethren, the glorious building of grace has its foundation, not on earth, where we are pilgrims and strangers, but in heaven, where Jesus, the corner-stone, "elect and precious," sitteth at the right hand of God, and is constantly occupied in gathering from afar the "lively stones" of the glorious edifice. Blessed forever be his holy name! YOUR THIRD PROOF. John 20:19, 26--"Then the same day at evening, being the first day of the week, when the doors were shut where the disciples were assembled for fear of the Jews, came Jesus and stood in the midst, and saith unto them, Peace be unto you." "And after eight days again his disciples were within, and Thomas with them; then came Jesus; the doors being shut, and stood in the midst, and said, Peace be unto you."--See also Luke 24:26. You premise, that the disciples, on the two days referred to above, one of which certainly was, and the other may have been, the first day of the week, had met together for public or social worship, when Christ appeared to them. Whence you infer, that the first day of the week is the Sabbath. Now, what you premise _seems_ to be a mere assumption, for which there is not a shadow of proof, either in the text or context. No one of the Evangelists says that they met for worship; nor did they worship, so far as we know, when met together. In regard to the first of those occasions, we are told, that they "were assembled for fear of the Jews;" and, as to the second, we are simply informed, that they "were within," which means, probably, that they were _at home_; for Luke tells us, that, on the day of the ascension, the eleven "abode" in an upper room. Acts 1:13.
