A few questions:

But foolish and unlearned questions avoid,
knowing that they do gender strifes.
2 Timothy 2:23
1) In John 20/21, Jesus told Peter "feed my lambs, feed my sheep, etc." Was Peter invisible at the time He said that?
Is Peter still deaf?

You also are a small rock,
able to make spiritual sacrifices acceptable to God by Jesus Christ.

Ye also, as lively stones,
are built up a spiritual house, an holy priesthood,
to offer up spiritual sacrifices, acceptable to God by Jesus Christ.

1 Peter 2:5

2) In Matthew 23:1-2, Jesus said to do what the Pharisees say, because they sit in Moses' seat. WEre the Pharisees invisible?
The Priests and Bishops are still deaf,
even to this day they still exercise power over the Gentiles.

But it shall not be so among you:
but whosoever will be great among you,
let him be your minister;
And whosoever will be chief among you,
let him be your servant:
Even as the Son of man came not to be ministered unto,
but to minister, and to give His life a ransom for many.
Matthew 20:26-28


3) Moses transmitted the 10 commandments and the laws to the people. Was Moses invisible?
Is the Lord invisible? that every eye shall see Him.
Even you who pierce?

But I said unto you,
That ye also have seen Me, and believe not.
John 6:36

The point is that God can exercise His infallible authority through fallible men.
You are the judge in His place.
And if you can judge angels, then how much more the things of this world?

Do ye not know that the saints shall judge the world?
and if the world shall be judged by you,
are ye unworthy to judge the smallest matters?
Know ye not that we shall judge angels?
how much more things that pertain to this life?

1 Corinthians 6:2-3

Also, I Timothy 3:15 is clear that the church is the pillar and ground of truth.
No,
the pillar and ground of truth is God's Church.

Any Church who calls themself His Church, but has not the truth,
is a liar and an hypocrite, and is satan's synagogue.

Howbeit in vain do they worship Me,
teaching for doctines the commandments of men.

Mark 7:7

The point is, don't bear false witness against God, by insisting that He did not set up human authorities, and that He is too weak to do that.
Blessed are the little rocks to whom God reveals His Son.

On this revelation He builds His Church
`Paul

And this is the will of Him that sent Me,
that every one which seeth the Son,
and believeth on Him,
may have everlasting life:
and I will raise him up at the last day.
John 6:40
