The Council of Chalcedon in 451 AD also.
After the Lord’s resurrection–which was certainly the resurrection of a real body, since the one brought back to life is none other than the one who had been crucified and had died–the whole point of the forty-day delay was to make our faith completely sound and to cleanse it of all darkness. Hence he talked to his disciples and lived and ate with them, and let himself be touched attentively and carefully by those who were in the grip of doubt; he would go in among his disciples when the doors were locked, and impart the holy Spirit by breathing on them, and open up the secrets of the holy scriptures after enlightening their understanding; again, he would point out the wound in his side, the holes made by the nails, and all the signs of the suffering he had just recently undergone, saying, Look at my hands and feet–it is I. Feel and see, because a spirit does not have flesh and bones as you see that I have. All this was so that it would be recognised that the proper character of the divine and of the human nature went on existing inseparable in him; and so that we would realise that the Word is not the same thing as the flesh, but in such a way that we would confess belief in the one Son of God as being both Word and flesh.
So, following the saintly fathers, we all with one voice teach the confession of one and the same Son, our Lord Jesus Christ: the same perfect in divinity and perfect in humanity, the same truly God and truly man, of a rational soul and a body; consubstantial with the Father as regards his divinity, and the same consubstantial with us as regards his humanity; like us in all respects except for sin; begotten before the ages from the Father as regards his divinity, and in the last days the same for us and for our salvation from Mary, the virgin God-bearer as regards his humanity; one and the same Christ, Son, Lord, only-begotten, acknowledged in two natures which undergo no confusion, no change, no division, no separation; at no point was the difference between the natures taken away through the union, but rather the property of both natures is preserved and comes together into a single person and a single subsistent being; he is not parted or divided into two persons, but is one and the same only-begotten Son, God, Word, Lord Jesus Christ, just as the prophets taught from the beginning about him, and as the Lord Jesus Christ himself instructed us, and as the creed of the fathers handed it down to us.
