What was left out? Nothing. But it has to be interpreted. Correct?
It is indeed possible for a person of good will, who is fervently seeking God's will above his own will, to figure out from the Scriptures which "church" he should be attending. However, if he is not willing to act on what he has learned, he will be spiritually worse off than when he was ignorant of the truth.
Luke 12:42-48
Jesus established a Church with a hierarchy to make disciples for Him and to teach these new disciples to obey all that He commands them. The Bible is not Christ's Church. The Bible is an inanimate object. It has no ears to hear, no eyes to see, and no brain to interpret itself. It can exercise no authority. Only people can hear, see, think, and exercise authority.
Jesus gave His authority and power for His Church's government and its continuation to His apostles and their successors. He gave to the apostles and disciples the Scriptures via the Holy Spirit's inspiration and He gave to them the authority and ability to interpret for His Church's disciples what the original authors meant to convey to His disciples.
When the Scriptures are interpreted by the legitimate authority appointed by Jesus Christ through hierarchical apostolic succession, they agree perfectly with the original apostles' and disciples' oral preaching.
Matthew 28:18-20
"And Jesus came and spoke to them, saying, All authority has been given to Me in heaven and on earth. 19 Go therefore and make disciples of all the nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, 20 teaching them to observe all things that I have commanded you; and lo, I am with you always,
even to the end of the age. Amen." NKJV
(To observe means
to obey.)
Luke writes about the first successor of the apostles in
Acts 1:15-26.
In OT times, Moses was given this governing authority from God. Later, Moses appointed judges/rulers to help him.
Exodus 18:12-26
By the time of Jesus, Moses' authority was exercised by the scribes (teachers of the Law) and the Pharisees. Since the OT was still in force and would remain in force until Jesus died on the cross, Jesus commanded that His followers obey the scribes and Pharisees because they alone exercised the authority of Moses.
Matthew 23:1-3
"Then Jesus said to the crowds and to his disciples: 2 The teachers of the law and the Pharisees sit in Moses seat. 3 So you must be careful to do everything they tell you. But do not do what they do, for they do not practice what they preach." NIV
Jesus established a Church with a hierarchy with Peter, to whom He gave the keys of the kingdom of heaven at the top, like Moses was for the Israelites; and the other apostles helping him like the judges and rulers helped Moses and He commanded His NC hierarchy to make disciples for Him by baptizing them
and to teach these new disciples to obey all that Jesus commanded them.
Matthew 28:18-20
Then Jesus came to them and said, All authority in heaven and on earth has been given to me. 19 Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, 20 and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age. NIV
Today, it is still Jesus' Church's hierarchy who has His authority to rule over the members of His Church. We cannot change this incontrovertible fact even if we do not personally like who these rulers are or how they act in their personal lives. Jesus commanded that His followers obey the scribes and Pharisees in matters of religion but He also told them not to imitate these sinful scribes' and Pharisee's personal actions.
Paul also commands this same thing for NC Christians:
Hebrews 13:7-8; 17
"Remember those who rule over you, who have spoken the word of God to you, whose faith follow,
considering the outcome of their conduct........ 17 Obey those who rule over you, and be submissive, for they watch out for your souls, as those who must give account. Let them do so with joy and not with grief, for that would be unprofitable for you." NKJV
In other words, if any one of the hierarchy's leaders does not do the commands of Jesus that he preaches to you, obey him in matters of religion, but do not imitate his lifestyle.
Jesus established one church only. He is its head. His disciples/followers are its body. He has appointed leaders for the making of disciples through baptism for Him and for the teaching of His gospel to them and for the governing of all His Church on earth.
Ephesians 4:4-6
"There is one body and one Spirit, just as you were called in one hope of your calling; 5 one Lord, one faith, one baptism; 6 one God and Father of all, who
is above all, and through all, and in you all." NKJV
Everyone who is legitimately baptized is a member of Jesus' body, His Church. (This is not the thread we should use to discuss more about baptism.)
However, not every baptized person understands and partakes of all that His Church has to offer. Jesus commands that we eat His real glorified Flesh and drink His real glorified Blood if we want to have eternal life. Many baptized persons do not have access to His real Flesh and real Blood in the places where they worship and so they are not doing as Jesus commanded in order to enter into eternal life.
John 6:47-58
"Very truly I tell you, the one who believes has eternal life. 48 I am the bread of life. 49 Your ancestors ate the manna in the wilderness, yet they died. 50 But here is the bread that comes down from heaven, which anyone may eat and not die. 51
I am the living bread that came down from heaven. Whoever eats this bread will live forever. This bread is my flesh, which I will give for the life of the world. 52
Then the Jews began to argue sharply among themselves, How can this man give us his flesh to eat?
53 Jesus said to them,
Very truly I tell you, unless you eat the flesh of the Son of Man and drink his blood, you have no life in you. 54 Whoever eats my flesh and drinks my blood has eternal life, and I will raise them up at the last day. 55 For my flesh is real food and my blood is real drink.
56 Whoever eats my flesh and drinks my blood remains in me, and I in them. 57 Just as the living Father sent me and I live because of the Father, so the one who feeds on me will live because of me. 58 This is the bread that came down from heaven. Your ancestors ate manna and died, but whoever feeds on this bread will live forever." NIV
Only the successors of the apostles are able to provide the real Flesh and the real Blood of Jesus Christ to His followers and it is only the Catholic and Orthodox Churches who have this unbroken succession from the apostles.
Paul ordained Timothy by the laying on of the hands of the eldership/priesthood and so later Paul writes to him to encourage him in his ministry:
1 Timothy 4:12-16
"Let no one despise your youth, but be an example to the believers in word, in conduct, in love, in spirit, in faith, in purity. 13 Till I come, give attention to reading, to exhortation, to doctrine. 14
Do not neglect the gift that is in you, which was given to you by prophecy with the laying on of the hands of the eldership. 15 Meditate on these things; give yourself entirely to them, that your progress may be evident to all. 16 Take heed to yourself and to the doctrine. Continue in them, for in doing this you will save both yourself and those who hear you." NKJV
I want to enter into eternal life and so I eat Jesus' real flesh and I drink His real blood as He commanded us to do and I partake of these gifts in a worthy manner.
1 Corinthians 11:23-27;
Matthew 5:22-24
