Jesus established His one true Church Himself during the incarnation.
- Appointed Simon, (now Peter/Petra/the Rock), as the visible head of His Church.
*From the Gospel of St. Matthew 16:
18And I say also unto thee, That thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it. *
- Jesus then gave Peter and the other Apostles the ability to carry out His own work here on earth
*From the Gospel of St. Matthew 16:
19And I will give unto thee the keys of the kingdom of heaven: and whatsoever thou shalt bind on earth shall be bound in heaven: and whatsoever thou shalt loose on earth shall be loosed in heaven.
From the Gospel of St. John 20:
21Then said Jesus to them again, Peace be unto you: as my Father hath sent me, even so send I you.
22And when he had said this, he breathed on them, and saith unto them, Receive ye the Holy Ghost:
23Whose soever sins ye remit, they are remitted unto them; and whose soever sins ye retain, they are retained. *
- Then…Jesus gave commanded them on what work they should do here on Earth:
*From the Gospel of St. Luke 22:
19 And he took bread, and when he had given thanks, he broke it and gave it to them, saying, “This is my body, which is given for you. Do this in remembrance of me.”
From the Gospel of St. Matthew 28:
19 Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, 20 teaching to observe all that I have commanded you. And behold, I am with you always, to the end of the age."
From the Gospel of St. Mark 16:
15 And he said to them, "Go into all the world and proclaim the gospel to the whole creation.*
Study and prayer on these passages helped open my eyes to the reality of His one Church.
Good place to start anyway. I’m sure you’ll get plenty of other good ideas as well.
Peace be with you.
