God was not writing to the pastor, the pastor is only part of the church.
That's exactly who Jesus was addressing. Not a "celestial angel", that doesn't fit the context. He addressed the pastor of the church of Ephesus.
Revelation 2:1-7
(1) Unto the angel of the church of Ephesus write; These things saith he that holdeth the seven stars in his right hand, who walketh in the midst of the seven golden candlesticks;
(2) I know thy works, and thy labour, and thy patience, and how thou canst not bear them which are evil: and thou hast tried them which say they are apostles, and are not, and hast found them liars:
(3) And hast borne, and hast patience, and for my name's sake hast laboured, and hast not fainted.
(4) Nevertheless I have somewhat against thee, because thou hast left thy first love.
(5) Remember therefore from whence thou art fallen, and repent, and do the first works; or else I will come unto thee quickly, and will remove thy candlestick out of his place, except thou repent.
(6) But this thou hast, that thou hatest the deeds of the Nicolaitans, which I also hate.
(7) He that hath an ear, let him hear what the Spirit saith unto the churches; To him that overcometh will I give to eat of the tree of life, which is in the midst of the paradise of God.
You are to intelligent to not to understand this!
Thank you! So then maybe I actually DO understand this, eh?
For as the body is one, and hath many members, and all the members of that one body, being many, are one body: so also is Christ.
13 For by one Spirit are we all baptized into one body, whether we be Jews or Gentiles, whether we be bond or free; and have been all made to drink into one Spirit.
14 For the body is not one member, but many.
15 If the foot shall say, Because I am not the hand, I am not of the body; is it therefore not of the body?
We are not talking about literal body parts, can your foot talk?
It's always, or so very often, right there in the context. Here,
1 Corinthians 12:13-19
(13)
For by one Spirit are we all baptized into one body, whether we be Jews or Gentiles, whether we be bond or free; and have been all made to drink into one Spirit.
(14) For the body is not one member, but many.
(15) If the foot shall say, Because I am not the hand, I am not of the body; is it therefore not of the body?
(16) And if the ear shall say, Because I am not the eye, I am not of the body; is it therefore not of the body?
(17) If the whole body were an eye, where were the hearing? If the whole were hearing, where were the smelling?
(18) But now hath God set the members every one of them in the body, as it hath pleased him.
(19) And if they were all one member, where were the body?
Paul defines what he's talking about. Here, we are baptized into a body, he's speaking of the body of Christ. And he goes on to use our personal bodies as a metaphor for His body.
Ephesians 5:25-30
(25) Husbands, love your wives, even as Christ also loved the church, and gave himself for it;
(26) That he might sanctify and cleanse it with the washing of water by the word,
(27) That he might present it to himself a glorious church, not having spot, or wrinkle, or any such thing; but that it should be holy and without blemish.
(28) So ought men to love their wives as their own bodies. He that loveth his wife loveth himself.
(29) For no man ever yet hated his own flesh; but nourisheth and cherisheth it, even as the Lord the church:
(30) For we are members of his body, of his flesh, and of his bones.
Here, the context is again plain. Men are to love their wives as they do their own body. That's not church, that's your hair and your toes and everything in between. Then he shifts the use, we are members of His body. The context tells you about each.
And again, Jesus,
Matthew 5:29-30
(29) And if thy right eye offend thee, pluck it out, and cast it from thee: for it is profitable for thee that one of thy members should perish, and not that thy whole body should be cast into hell.
(30) And if thy right hand offend thee, cut it off, and cast it from thee: for it is profitable for thee that one of thy members should perish, and not that thy whole body should be cast into hell.
Context again informs us of what he's talking about, it's your eye, your hand, if they cause you to sin, cut them off, better that than your whole body be tossed into hell.
Of course, Jesus said, "If your eye cause you to sin", but is it your eye that causes sin? Or is it the flesh? We have to cut off the flesh and cast it away.
Now, you can, and many do, interpret
allegorically/metaphorically/spiritually/however you want to characterize it as though Jesus intended that His message would be understood to be instucting to cast out the church-goer who causes others to sin, lest the rest of the church be cast into hell, and all salvation lost, but the wording of the text simply isn't there.
Much love!
Fear and bondage to IN-security is no way to live the Christian life. After my conversion I now have assurance of salvation (1 John 5:11-13) and I walk with the Lord out of love and gratitude for everything He has done for me. (Romans 5:5; 1 John 4:7,19) Praise God!
