If the church is driven by the will of individuals...
We see it as the Church is something that Christ willed and founded, therefore it is Perfect and Indefectible, and something that man aspires to. The Church endures, She is an ark, we are both the people carried in Her, and the storms that rage about Her ... any fault is ours, not hers.
I would say the Church marks the degree to which human will falls short of what it would and could be. The Church is driven by the Will of Christ, no other ... we didn't decide what She is, He did ... we do not will it, but aspire to it ... usually, badly, but sometimes, gloriously.
then as they err then so does the church. If the individuals represent the church, then as they err, so does the church.
No. Not if the error is willed by the individual, and not by the Church. A bent copper does not render the law invalid. It might make its admin procedure subject to review, but the principle of the law remains inviolate.
If the church is not represented by individuals or will, then I presume we are talking about something abstract and immaterial? In which case, we are neither talking about the RCC nor any other denomination?
No, only if Jesus Himself is abstract and immaterial ... as many assume Him to be ... but we believe He walked and talked, and we have the testimony of those He called.
Christ is His Church ... without Christ, there is no Church, and without the Church, there is no Christ ...
I would argue that the Catholic Church
alone is the one who has placed no human, rational, determination or limitation on what is possible for Her founder, according to the Word of Scripture. I would further argue that every other church, whilst child of the one Mother Church, is defective to the degree of human discrimination that altered or revoked the original doctrine.
Now we are not perfect, none of us, so there will always be sin in her members, but in Herself, She is eternally perfected, so that for the seeker, there is no limitation to the spirit of sonship promised of Her founder, rather there are the sacraments that realise, as best we can in this world, the beatitude promised of the next.
The contra argument will always seek to rationalise what the Church is, to reduce it to a philosophical or ethical institution ... and the Catholic will always shake his head ... She is a Mystery.
