I would say not the faith of Abraham but the faith of Christ .We are not to have faith God as the things of God after the things of men .Many abuse the word Abraham in that way making it about his flesh
I would offer that Christ came to bring division and establish as unseen a union by grace.We do not wrestle against the things seen.
Non-denominational is a denomination/sect as a part of the whole. God typified as Abraham is considered the God or father of many nations, as denominations/sects. Abraham is the literal father of one nation.
No such thing as no separation in thought between even one man with another .Our thoughts are not His thoughts and neither our our ways, his . If a person is married they get it. Or one sects thoughts with another.
That idealism is reserved for the father and Son alone.He is are of one mind and always does whatsoever His soul pleases .it is he who makes our hearts softer.
We all have our differences as fingerprints. Seeing it is God who does make us different from one another there is no self-made/created men, when it comes to new creatures.
We walk by faith, the unseen eternal. The kingdom of God is not of this world, again we walk (understand) by the unseen eternal as we are informed in 2 Corinthian 4:18 .
He is the power that binds men to do His will as His Spirit works in us..
In reality when two or three gather together under the authority of his living word he is there. Two or three constitutes a sect with Christ as the head. .A family that gathers together in the authority or power of the gospel that each member has in these earthen bodies (not of them) differs in their opinion from a family next door. They both can be considered a sect.
Mat 18:20 For where two or three are gathered together in my name, there am I in the midst of them.
From my experiences Catholicism has done much damage because they change the meaning of words to take away the authority of scripture.
They would say they are not a sect and call every denomination but their own heretics. the same with the phrase private interpretation .They say every other sect other than their own has one, as heresy, as a opinion .Taking away the authority when two or three, or two million and three million men gather together.
The word denomination or sect is derived from the word heresy which is simply an opinion or private interpretation as a personal commentary on what each individual thinks the Holy Spirit is revealing as they do seek after His approval .
In that way Christ informs us there must be heresies as differences of opinion among us

1Corinthians 11:19 For there must be also heresies among you, that they which are approved may be made manifest among you.
The heresies that are damnable or judge-able in respect to the gospel that we are to be careful of ...flat out deny the fullness of the grace of Christ, The Catholics are noted for that offering that Christ only gives a unknown "remnant of grace" with the remaining remnant under the idea of personal suffering for a unknown amount of time ,or severity in a unknown place called Purgatory. It make the grace of Christ without effect by doing despite to the Spirit of grace.
2Peter 2:1 But there were false prophets also among the people, even as there shall be false teachers among you, who privily shall bring in damnable heresies, even denying the Lord that bought them, and bring upon themselves swift destruction.
