The apostles were the ones instructed by Jesus, and then with the help of the Holy Spirit, they were inspired to spread the word throughout the land, after Jesus had died and was risen. This wasn't going to be easy, as you'll see from this first reading from the Acts of the Apostles....
27 Having brought the apostles, they made them appear before the Sanhedrin to be questioned by the high priest.
28 "We gave you strict orders not to teach in this name (Jesus)," he said. "Yet you have filled Jerusalem with your teaching and are determined to make us guilty of this man's blood."
29 Peter and the other apostles replied: "We must obey God rather than men!
30 The God of our fathers raised Jesus from the dead—whom you had killed by hanging him on a tree.
31 God exalted him to his own right hand as Prince and Savior that he might give repentance and forgiveness of sins to Israel.
32 We are witnesses of these things, and so is the Holy Spirit, whom God has given to those who obey him."
33 When they heard this, they were furious and wanted to put them to death.
34 But a Pharisee named Gamaliel, a teacher of the law, who was honored by all the people, stood up in the Sanhedrin and ordered that the men be put outside for a little while.
35 Then he addressed them: "Men of Israel, consider carefully what you intend to do to these men. 36 Some time ago Theudas appeared, claiming to be somebody, and about four hundred men rallied to him. He was killed, all his followers were dispersed, and it all came to nothing.
37 After him, Judas the Galilean appeared in the days of the census and led a band of people in revolt. He too was killed, and all his followers were scattered.
38 Therefore, in the present case I advise you: Leave these men alone! Let them go! For if their purpose or activity is of human origin, it will fail.
39 But if it is from God, you will not be able to stop these men; you will only find yourselves fighting against God."
40 His speech persuaded them. They called the apostles in and had them flogged. Then they ordered them not to speak in the name of Jesus, and let them go.
41 The apostles left the Sanhedrin, rejoicing because they had been counted worthy of suffering disgrace for the Name of Jesus.
42 Day after day, in the temple courts and from house to house, they never stopped teaching and proclaiming the good news that Jesus is the Christ.
In the second reading, we hear more from John about his visionary dream in Revelation....
6 Then I saw a Lamb, looking as if it had been slain, standing in the center of the throne, encircled by the four living creatures and the elders. He had seven horns and seven eyes, which are the seven spirits of God sent out into all the earth.
7 He came and took the scroll from the right hand of Him who sat on the throne.
8 And when He had taken it, the four living creatures and the twenty-four elders fell down before the Lamb. Each one had a harp and they were holding golden bowls full of incense, which are the prayers of the saints.
9 And they sang a new song:
"You are worthy to take the scroll and to open its seals, because You (Jesus) were slain, and with Your blood You purchased men for God from every tribe and language and people and nation.
10 You have made them to be a kingdom and priests to serve our God, and they will reign on the earth."
11 Then I looked and heard the voice of many angels, numbering thousands upon thousands, and ten thousand times ten thousand. They encircled the throne and the living creatures and the elders.
12 In a loud voice they sang:
"Worthy is the Lamb, who was slain, to receive power and wealth and wisdom and strength and honor and glory and praise!"
13 Then I heard every creature in heaven and on earth and under the earth and on the sea, and all that is in them, singing:
"To Him who sits on the throne and to the Lamb (Jesus) be praise and honor and glory and power,
for ever and ever!"
14 The four living creatures said, "Amen," and the elders fell down and worshiped.
Jesus appears to His disciples a third time after His death, to once again help, instruct and reassure them....
Jesus and the Miraculous Catch of Fish
1 Afterward Jesus appeared again to his disciples, by the Sea of Tiberias. It happened this way:
2 Simon Peter, Thomas (called Didymus), Nathanael from Cana in Galilee, the sons of Zebedee, and two other disciples were together.
3 "I'm going out to fish," Simon Peter told them, and they said, "We'll go with you." So they went out and got into the boat, but that night they caught nothing.
4 Early in the morning, Jesus stood on the shore, but the disciples did not realize that it was Jesus.
5 He called out to them, "Friends, haven't you any fish?" "No," they answered.
6 He said, "Throw your net on the right side of the boat and you will find some." When they did, they were unable to haul the net in because of the large number of fish.
7 Then the disciple whom Jesus loved said to Peter, "It is the Lord!" As soon as Simon Peter heard him say, "It is the Lord," he wrapped his outer garment around him (for he had taken it off) and jumped into the water.
8 The other disciples followed in the boat, towing the net full of fish, for they were not far from shore, about a hundred yards.
9 When they landed, they saw a fire of burning coals there with fish on it, and some bread.
10 Jesus said to them, "Bring some of the fish you have just caught."
11 Simon Peter climbed aboard and dragged the net ashore. It was full of large fish, 153, but even with so many the net was not torn.
12 Jesus said to them, "Come and have breakfast." None of the disciples dared ask Him, "Who are you?" They knew it was the Lord.
13 Jesus came, took the bread and gave it to them, and did the same with the fish.
14 This was now the third time Jesus appeared to His disciples after He was raised from the dead.
Jesus Reinstates Peter
15 When they had finished eating, Jesus said to Simon Peter, "Simon son of John, do you truly love Me more than these?" "Yes, Lord," he said, "you know that I love You." Jesus said, "Feed My lambs."
16 Again Jesus said, "Simon son of John, do you truly love Me?" He answered, "Yes, Lord, you know that I love You." Jesus said, "Take care of My sheep."
17 The third time He said to him, "Simon son of John, do you love Me?"
Peter was hurt because Jesus asked him the third time, "Do you love Me?" He said, "Lord, You know all things; You know that I love You." Jesus said, "Feed My sheep.
18 I tell you the truth, when you were younger you dressed yourself and went where you wanted; but when you are old you will stretch out your hands, and someone else will dress you and lead you where you do not want to go."
19 Jesus said this to indicate the kind of death by which Peter would glorify God. Then He said to him, "Follow Me!"
20 Peter turned and saw that the disciple whom Jesus loved was following them. (This was the one who had leaned back against Jesus at the supper and had said, "Lord, who is going to betray You?")
21 When Peter saw him, he asked, "Lord, what about him?"
22 Jesus answered, "If I want him to remain alive until I return, what is that to you? You must follow Me."
23 Because of this, the rumor spread among the brothers that this disciple would not die. But Jesus did not say that he would not die; he only said, "If I want him to remain alive until I return, what is that to you?"
24 This is the disciple who testifies to these things and who wrote them down. We know that his testimony is true.
25 Jesus did many other things as well. If every one of them were written down, I suppose that even the whole world would not have room for the books that would be written.John 21:1-25
