What does it mean by holding to the Lord's Supper ?
The Mads who hold to it (which is most Mads) believe it is for the Body to partake in. They will take some time within their assemblies and do just that.
And these are Mads who's Pastor-Teachers are often very well grounded in how to study things out in Scripture from a consistently Mid-Acts Perspective.
Mid-Acts Bible Study being a perspective that began to re-emerge as a result of studying the Scripture through the Scripture, (rather than through the traditions of men), that first began to be recovered on a much more public scale all the way back to Martin Luther...
Only to be drowned out once more by the tendency of men toward a mix of empiricism and rationalism, in contrast to the purer form of studying the Scripture - through Scripture itself.
Even within Mad, some will be observed as having dropped the one for the other, in their attempt to understand one thing or another in Scripture.
From what I have observed - what those who have ended dropping the one for the other all have in common - there recurrent pattern - is their having attempted to solve for seemingly perplexing passages a bit to soon in their learning curve.
They were not sufficiently grounded in certain areas before they ventured off into those seemingly more perplexing ones on their own.
Sort of like why Martin Luther had been so thrown by the book of James.
He simply ventured into attempting to solve for its seeming contradiction to Romans 4 a bit too soon in what had essentially been new to him.
In the end, both his peers and those who came after him, ended up at the doorstep of rationalism for their "solution" to James 2 and Romans 4.
Which is then made a "tradition" together with a built in anathema against anyone who differs.
One would think such one sidedness would itself be a signal to such that they have wondered off a much sounder path.
But such is not often the case.
The result?
Dividing that is anything but "rightly."
Division between saints.
As Paul noted "THIS is NOT the Lord's supper..."
Such a divisive "my way or the highway" is not the spirit of the Lord's Supper - not the intended attitude in said "ordinance" He had intended as to the saint's in their dealings with one another "when ye come together."
Good question, bro.
