I'm not interested in your question about breaking bread in your meetings, do what you will amongst your own, it's between you and God. The early disciples and early Christians did quite a few things that got them told off, one of them being the pursuit of rank and hierarchy, something Jesus did not condone and which Paul and John rebuked.
Function yes, hierarchy no!
Gal 2:6
(6) But of these who seemed to be somewhat, (whatsoever they were, it makes no matter to me: God accepts no man's person:) for they who seemed to be somewhat in conference added nothing to me:
3Jn 1:9-10
(9) I wrote unto the church: but Diotrephes, who loves to have the preeminence among them, received us not.
(10) Wherefore, if I come, I will remember his deeds which he does, prating against us with malicious words: and not content therewith, neither does he himself receive the brethren, and forbids them that would, and casts them out of the ekklesia.(Written to Gaius)
Luk 22:24-26
(24) And there was also a strife among them, which of them should be accounted the greatest.
(25) And he said (Jesus) unto them, The kings of the Gentiles exercise lordship over them; and they that exercise authority upon them are called benefactors.
(26) But you shall not be so: but he that is greatest among you, let him be as the younger; and he that is chief, as he that does serve.
It is obvious Paul didn't bestow titles or elevate his co-workers to fanciful positions.
Php 4:2-3
(2) I beseech Euodias, and beseech Syntyche, that they be of the same mind in the Lord.
(3) And I intreat thee also, true yokefellow, help those women which laboured with me in the gospel, with Clement also, and with other my fellowlabourers, whose names are in the book of life.
Php 2:19-25
(19) But I trust in the Lord Jesus to send Timotheus shortly unto you, that I also may be of good comfort, when I know your state.
(20) For I have no man likeminded, who will naturally care for your state.
(21) For all seek their own, not the things which are Jesus Christ's.
(22) But you know the proof of him, that, as a son with the father, he has served with me in the gospel.
(23) Him therefore I hope to send presently, so soon as I shall see how it will go with me.
(24) But I trust in the Lord that I also myself shall come shortly.
(25) Yet I supposed it necessary to send to you Epaphroditus, my brother, and companion in labour, and fellowsoldier, but your messenger, and he that ministered to my wants.
The gathering for simple in-home fellowship of Christ-followers has continued from the Last Supper, to the upper room of Acts 1:13, to this present day. FYI, our lot don't meet in a basement.
