There isn't.
Clearly not.
Yep.
If that were true, then this op would not exist. Each denomination, sect, and cult claim to listen to Jesus, and each claim to do what you cited. Clearly, they do not do so the same.
I will suggest o everyone that the existence of diversity - even to the point of denominational or sectarian difference - is wholly scriptural and can be understood as either by God's design or acceptable to God. The undeniable precedent established in scripture is the fact the congregations in the various cities all had differences and their experience of Christ meant facing different circumstances and challenges relevant to their locale. Likewise, the teachings of Paul, Apollos, Peter, James, and all the others held to a core set of precepts while also asserting some diversity. It is also true that the apostolic leaders themselves changed as they applied the gospel in real life. Simply put, there is only one Church, and it was a very messy place. It remains so to this day and that should not surprise anyone who has read the Bible. There were many beliefs that needed correction, many practices that need to be discarded or replaced, and many false teachers. The same holds true to this day only now there are four billion people laying claim to the name of Christ (more if we count the cults) and not just a comparatively few a small portion of the world surrounding the Mediterranean. Most of us have never had to deal with the temple next door holding wild celebrations inhabited by ritual prostitution or human sacrifices (or both
). Even the regenerate apostles Paul and Peter disagreed and needed all that Paul wrote about in Ephesians 4. To some degree this op could be understood as a "first-world" problem, proof of the gospel's victory, and evidence of the Church's faithfulness and progress toward unity.
James 1:27
Pure and undefiled religion in the sight of our God and Father is this: to visit orphans and widows in their distress, and to keep oneself unstained by the world.
That is the religion of Jesus. Once the gospel is accepted that becomes what is expected as far as the religion goes. Other verses also inform the religious nature of the ecclesia.
Ephesians 4:11-16
And He gave some as apostles, and some as prophets, and some as evangelists, and some as pastors and teachers, for the equipping of the saints for the work of service, to the building up of the body of Christ; until we all attain to the unity of the faith, and of the knowledge of the Son of God, to a mature man, to the measure of the stature which belongs to the fullness of Christ. As a result, we are no longer to be children, tossed here and there by waves and carried about by every wind of doctrine, by the trickery of men, by craftiness in deceitful scheming; but speaking the truth in love, we are to grow up in all aspects into Him who is the head, even Christ, from whom the whole body, being fitted and held together by what every joint supplies, according to the proper working of each individual part, causes the growth of the body for the building up of itself in love.
None of that would be necessary if the transformative power of the gospel was instantaneous. God, in His omnipotent power, could have made it otherwise but God, in His infinite wisdom, did not do so. You and I live in a divided religion for a reason, just as we live in this time and place by God's design and for His purpose. There have always been variations within orthodoxy. There have always been look-a-likes and doppelgangers. There have always been competing paganisms. There have always been wheat growing among the weeds. There has always been the call to holiness within those contexts.
