19 On the evening of that day, the first day of the week, the doors being locked where the disciples were for fear of the Jews, Jesus came and stood among them and said to them, “Peace be with you” (Jn 20:19).
According to a popular interpretation, Jesus dematerialized, passed through the locked doors, then rematerialized on the other side. A fundamental problem with this interpretation is that it threatens the physicality of the Resurrection, which John is at pains to accentuate.
Here are some scriptural examples of how embodied people miraculously get past physical barriers:
21 Then Moses stretched out his hand over the sea, and the Lord drove the sea back by a strong east wind all night and made the sea dry land, and the waters were divided. 22 And the people of Israel went into the midst of the sea on dry ground, the waters being a wall to them on their right hand and on their left (Exod 14:21-22).
13 And when the soles of the feet of the priests bearing the ark of the Lord, the Lord of all the earth, shall rest in the waters of the Jordan, the waters of the Jordan shall be cut off from flowing, and the waters coming down from above shall stand in one heap.”
14 So when the people set out from their tents to pass over the Jordan with the priests bearing the ark of the covenant before the people, 15 and as soon as those bearing the ark had come as far as the Jordan, and the feet of the priests bearing the ark were dipped in the brink of the water (now the Jordan overflows all its banks throughout the time of harvest), 16 the waters coming down from above stood and rose up in a heap very far away, at Adam, the city that is beside Zarethan, and those flowing down toward the Sea of the Arabah, the Salt Sea, were completely cut off. And the people passed over opposite Jericho. 17 Now the priests bearing the ark of the covenant of the Lord stood firmly on dry ground in the midst of the Jordan, and all Israel was passing over on dry ground until all the nation finished passing over the Jordan (Josh 3:13-17).
8 Then Elijah took his cloak and rolled it up and struck the water, and the water was parted to the one side and to the other, till the two of them could go over on dry ground (2 Kgs 2:8).
18 they arrested the apostles and put them in the public prison. 19 But during the night an angel of the Lord opened the prison doors and brought them out, and said, 20 “Go and stand in the temple and speak to the people all the words of this Life.” 21 And when they heard this, they entered the temple at daybreak and began to teach.
Now when the high priest came, and those who were with him, they called together the council, all the senate of the people of Israel, and sent to the prison to have them brought. 22 But when the officers came, they did not find them in the prison, so they returned and reported, 23 “We found the prison securely locked and the guards standing at the doors, but when we opened them we found no one inside" (Acts 5:18-23).
4 And when he had seized him, he put him in prison, delivering him over to four squads of soldiers to guard him, intending after the Passover to bring him out to the people. 5 So Peter was kept in prison, but earnest prayer for him was made to God by the church.
6 Now when Herod was about to bring him out, on that very night, Peter was sleeping between two soldiers, bound with two chains, and sentries before the door were guarding the prison. 7 And behold, an angel of the Lord stood next to him, and a light shone in the cell. He struck Peter on the side and woke him, saying, “Get up quickly.” And the chains fell off his hands. 8 And the angel said to him, “Dress yourself and put on your sandals.” And he did so. And he said to him, “Wrap your cloak around you and follow me.” 9 And he went out and followed him. He did not know that what was being done by the angel was real, but thought he was seeing a vision. 10 When they had passed the first and the second guard, they came to the iron gate leading into the city. It opened for them of its own accord, and they went out and went along one street, and immediately the angel left him (Acts 12:4-10).
26 and suddenly there was a great earthquake, so that the foundations of the prison were shaken. And immediately all the doors were opened, and everyone's bonds were unfastened (Acts 16:26).
In not a single case does this involve a body dematerializing then rematerializing.
