One of the meanings of "apostolic church" is the apostolic succession of which the Church is believed to be the inheritor of.
Restricting oneself to Scripture alone is a possible approach and has its merits, but it may not be the fullest approach to Christianity.
I think that is a good point. The ritual of laying on of hands, the physical touch involved, speaks well of a sacramental church, in which the kingdom of God refers not to the ultimate passing of this world of (physical) touch, but the redemption of it, a resoration and re-opening of a new earthly Garden of Eden as it were, where living with God in harmony, atonement, at-One-ment even, becomes possible, here and now, in our world.
The kingdom of God is at hand even now.
There is a sacred trust involved as well in touch, an agreement to fidelity to one another, being of one mind, of one hearto, of one will.. To become of one flesh through touch becomes in a sense adultery when one becomes untrue to the truths that are passed down, apostle to bishop, to bishop. ....
In other words if and when the touch does not signify a passing on of teaching the same, then one must ask who else is laying on the hands and touching the bishops with ideas and dogma and doctrine that clearly have not come from the apostles?
On the one hand, one might say that there is rebellion against the One True Church on behalf of heretics, as in fact was being claimed.
On the other hand, one might say that it is not the apostolic tradition that is being broken with, but that different traditions come about as a result of having someone other than the apostles doing the touching and the ....pawing.
The point of Sola Scripture, I would hope, would be to introduce a little humility back into the discussion between a schismed church, to recognize that adherence to one Tradition or another cannot be the definition of what makes one a heretic. Different traditions cannot be the norm because different traditions have been with the church from the very beginning.
Perhaps it is inevitable that this is so, as the teachings of the twelve interact with the cultural understandings of the varied people that they come into contact with throughout the whole of the known world, even in one generation.
Actually I don't think that you would disagree with me too strongly on that point anyway.
