Jesus left us with a Church and the Holy Spirit. He entrusted the Church to spread His Truth (His Doctrine). He did not even write it down or ask people to write it down.
Nice try.
Except for this........
Revelation 1:17-19 17 When I saw him, I fell at his feet as though dead. But he laid his right hand on me, saying, “Fear not, I am the first and the last, 18 and the living one. I died, and behold I am alive forevermore, and I have the keys of Death and Hades. 19 Write therefore the things that you have seen, those that are and those that are to take place after this.
In all, that argument against the written word of Scripture is a bunch of nonsense. Jesus never said that the church was the means by which we were to know about Him either and to pass down by oral tradition His teachings.
God is a BIG fan of the written word, since you haven't noticed.
Exodus 17:14 Then the LORD said to Moses, “Write this as a memorial in a book and recite it in the ears of Joshua, that I will utterly blot out the memory of Amalek from under heaven.”
Exodus 34:1 The LORD said to Moses, “Cut for yourself two tablets of stone like the first, and I will write on the tablets the words that were on the first tablets, which you broke.
Exodus 34:27 And the LORD said to Moses, “Write these words, for in accordance with these words I have made a covenant with you and with Israel.”
Deuteronomy 11:19-21 19 You shall teach them to your children, talking of them when you are sitting in your house, and when you are walking by the way, and when you lie down, and when you rise. 20 You shall write them on the doorposts of your house and on your gates, 21 that your days and the days of your children may be multiplied in the land that the Lord swore to your fathers to give them, as long as the heavens are above the earth.
Deuteronomy 27:3 And you shall write on them all the words of this law, when you cross over to enter the land that the LORD your God is giving you, a land flowing with milk and honey, as the LORD, the God of your fathers, has promised you.
Deuteronomy 27:8 And you shall write on the stones all the words of this law very plainly.”
Matthew 4:4 But he answered, “It is written, “‘Man shall not live by bread alone, but by every word that comes from the mouth of God.’”
Matthew 4:7 Jesus said to him, “Again it is written, ‘You shall not put the Lord your God to the test.’”
Matthew 4:10 Then Jesus said to him, “Be gone, Satan! For it is written, “‘You shall worship the Lord your God and him only shall you serve.’”
Jesus used the written word to defeat Satan's attempts to tempt Him. He succeeded where Adam and Eve had failed.
In the garden, the first thing Satan did was attack the word God had given them. Adam passed it to Eve verbally, ONE command, and she got it wrong.
By appealing to the authority of the WRITTEN word, there was no chance that Jesus would do that. God's word is settled in heaven forever.
These are all the times that *It is written....* is listed in the NT.
But nobody can stop you from trusting your church to save you and following it. Let us know how that works out for you because even most Catholics I know aren't even sure if they're going to get into heaven.
I'll stick with the surety that faith in Christ gives us.
John 20:30-31 30 Now Jesus did many other signs in the presence of the disciples, which are not written in this book; 31 but these are written so that you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in his name.
1 John 5:13 I write these things to you who believe in the name of the Son of God that you may know that you have eternal life.
Word of mouth is absolutely the least reliable means of communicating ANYTHING especially an organization with the history of corruption that the RCC has. It's absolute folly to depend on that instead of the written word that God gave us.
