I think that sometimes as the bible said sects are something the flesh creates. other times sects might be more kin to the different parts of the body of Christ.
the mind of Christ is key to ruling over the natural process that the flesh has, which it has for the sake of survival because that is what flesh creatures do in this world.
1Pet 2:11 (YLT)
Beloved, I call upon you , as strangers and sojourners, to keep from the fleshly desires, that war against the soul,
1Pet 3:18 (YLT)
because also Christ once for sin did suffer--righteous for unrighteous--that he might lead us to God, having been put to death indeed, in the flesh, and having been made alive in the spirit,
1Pet 4:1 (YLT)
Christ, then, having suffered for us in the flesh, ye also with the same mind arm yourselves, because he who did suffer in the flesh hath done with sin,
1 John 4:2 (YLT)
in this know ye the Spirit of God; every spirit that doth confess Jesus Christ in the flesh having come, of God it is,
1Tim 3:16 (YLT)
and, confessedly, great is the secret of piety--God was manifested in flesh, declared righteous in spirit, seen by messengers, preached among nations, believed on in the world, taken up in glory!
Col 2:13 (YLT)
And you--being dead in the trespasses and the uncircumcision of your flesh--He made alive together with him, having forgiven you all the trespasses,
Eph 5:29-33 (YLT)
for no one ever his own flesh did hate, but doth nourish and cherish it, as also the Lord--the assembly, because members we are of his body, of his flesh, and of his bones;
`for this cause shall a man leave his father and mother, and shall be joined to his wife, and they shall be--the two--for one flesh;' this secret is great, and I speak in regard to Christ and to the assembly;
but ye also, every one in particular--let each his own wife so love as himself, and the wife--that she may reverence the husband.
