In Romans 14 Paul wrote about the believers who saw one another in the Agora or Marketplace: the MARK of the three sects was where you saw them buying their food often taking their meals in the common kitchens. The mark of all of the sects was that they wanted to impose doubtful disputations but Paul restricted the common assembly in Romans 15 to edification or education. In a religious sense rather than in their personal lives;
Romans 14:23 And he that doubteth is damned if he eat, because he eateth not of faith: for whatsoever is not of faith is sin
THE FAITH comes by hearing the WORD of God: that is thee LOGOS defined as God's regulative principle. If you are commanded to teach only "that which is written for our learning" and commanded to use one mind and one mouth, you need to understand how LOGOS is used. It is the opposite of PATHOS or personal opinions or personal experiences, it is opposite to Rhetoric, singing, playing instruments or acting.
Paul uses "synagogue" words to define assemblying, gathering or coming together: we know from Numbers that the Spirit OF Christ silenced "vocal or instrumental rejoicing" which includes high-sounding rhetoric. The Synagogue was a WORD OF GOD ONLY assembly: they had no praise service because it was forbidden and because anyone should know that SPEAKING the Word does not fit with playing instruments. So, out of respect for the commandment, God and His Word and others who are "enchanted or sorcererized" by instrumental sounds. Recent studies have proven that a vast number of people will never attend any music- or rhetoric-focused assembly because they suffer from AHEDONIA which means that they are damaged by what others think is cute, talented or entertainment.
So, believe Scripture and church history before superstitious LITURGY as human WORKS was imposed by people who got paid and convinced you that they are the mediators in song and sermon when Scripture says that the Man Jesus Christ is the only Mediator. That is why we honor the key commandment of Jesus to make disciples by teaching and baptizing and then TEACHING them what HE commanded to be taught. Jesus was musically mocked by the Jewish clergy in prophecy and in fact.
If Christ in the Prophets and Apostles did not teach but condemned all performers, and the Church is built upon or EDUCATED by the Prophets and Apostles, and the assembly is defined for EDUCATION or learning only, then everyone gets to decide whether they have the right to IMPOSE (mosly during and follwoing the frontier revivals) instrumental sounds because they found out: YES, it is true: we can induce a "saved" spell of ecstasy simply by using mechanical sounds and the drum-beat rhythm. However, is you IMPOSE something as the "works of human hands" and are expending ERGS or units of talent and work, doesn't that mean that you are a legalist and believe that, as with people from the cave and beyond, you can control or aid the "gods" by your own effort?
I can post God's asssociation between instrumental sounds and telling God "we will not obey" (Ezek 33, Job 21) all day long and no one can find a single example in the Bible or for centuries in church history where God wants to call you out of your REST to engage in congregational or group-performance singing with or without instruments. So, where would anyone suddenly get the notion that God COMMANDS instrumental praise which is just what the Shaman said and says?
It is a recorded fact that the music "thingy" has been the primary creator of discord since unwashed Bishops from Syrian introduced singing c. ad 393 and thereby split the East from the West Church to this day. Even simple people objected because they understand that SPEAK that which is written to teach and admonish did not mean SING that which which the bishop wrote even if in the form of "bible stories."
To Ephraim pertains the high and unique distinction of having originated-or at least given its living impulse to-
a new departure in sacred literature; and that, not for his own country merely, but for Christendom.
From him came, if not the first idea, at all events the first successful example,
of making song an essential constituent of public worship,
and an exponent of theological teaching;
and from him it spread and prevailed through
the Eastern Churches, and affected even those of the West.
To the Hymns, on which chiefly his fame rests, the Syriac ritual in all its forms owes much of its strength and richness;
and to them is largely due the place which Hymnody holds throughout the Church everywhere.
