This issue is just an example of the whole argument. We see individuals
who believe they have the authority of God and Holy Spirit. They determine what is scripture or not, what the meaning of Holy Scripture is, what are correct dogma and doctrine, soteriology, etc. in the stead of Christ’s Apostles and the Church.
They are the Church, they say, they are ‘thinking God’s thoughts’, they can even tell who is saved and who is doomed to hell.
The argument often is not so much against the Church, but against anyone or anything other than themselves being the Church; they are the sole determinant of the Christian Faith and beyond.
It is individualism taken to such heights as to be indistinguishable from megalomania.
Your argument isn’t with us. It’s with scripture.
Romans 8:10: Paul tells us, "If Christ is in you, the body is dead because of sin." Galatians 2:20: Paul speaks of himself and all true Christians: "I have been crucified with Christ; it is no longer I who live, but Christ lives in me." Ephesians 3:17-18: Referring to the "inner man," Paul mentions that he prays "that Christ may dwell in your hearts through faith." I John 3:24: John writes: "Now he who keeps His commandments abides in Him, and He in him. And by this we know that He abides in us, by the Spirit which He has given us."
Galatians 3:27 For as many of you as have been baptized into Christ have put on Christ.
2 Corinthians 1:22 Who hath also sealed us, and given the earnest of the Spirit in our hearts.
Now, if you don’t think that Christians have the “mind of Christ in you” maybe you have more serious problems.
Romans 8:9 But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his.
John 14:17 Even the Spirit of truth; whom the world cannot receive, because it seeth him not, neither knoweth him: but ye know him; for he dwelleth with you, and shall be in you.
And we see individuals who choose to be Catholic who also make their own determination of what is Scripture and what is not by conceding to what others have decided on the matter. Their only decision is to let someone else decide for them.
So a group of men come alone sometime in the 300's AD, self-proclaim to be in line with apostolic succession and self declare authority from that. They then demand that everyone recognize their self-proclaimed authority and proclaim anathemas for those who do not fall in line.
They are the Church, they say, they are ‘thinking God’s thoughts’, they can even tell who is saved and who is doomed to hell.
Again, nothing that Catholics don't do on a regular basis.
It is individualism taken to such heights as to be indistinguishable from megalomania.
1 Corinthians 12:11 All these are empowered by one and the same Spirit, who apportions to each one individually as he wills.
1 Corinthians 12:27 Now you are the body of Christ and individually members of it.
