I'd have to disagree on the first issue, whether doctrine should be uniform or not. But, I'd agree with most of your view. Not sure if a post or two will make you and I of one mind, but it's worth a shot, right?
I'd say first, wouldn't it be wonderful if Catholics gave heed to the above teaching?
Secondly, I take the view that each believer will be specifically judged according to his/her understanding of the Scripture and the will of God for their lives. This does not mean I include non-Christian cults and sects as valid, but, the following passage takes place within this Age:
Acts 11
34 Then Peter opened his mouth, and said, Of a truth I perceive that God is no respecter of persons:
35 But in every nation he that feareth him, and worketh righteousness, is accepted with him.
Keep in mind that the New Covenant is in full effect, and this man is presented as one that God holds in consideration. Like most of us when we are born again, he knows nothing of Christian doctrine that we are told.
This is one thing.
Going back to the original issue (being of one mind), consider:
Romans 14
King James Version
14 Him that is weak in the faith receive ye, but not to doubtful disputations.
The chapter seems to make it clear that we are to receive those that are weak in the faith, but it points out—they are weak in the faith. And I think this first verse tells us not to receive their views. The wording here can be taken numerous ways, but one of the things we have to guide us in our interpretations is the rest of Scripture. At no time did Paul fail to correct in doctrinal matters. Nor, for that matter, in behavioral issues. Thus, we do not question their salvation, but we do not accept their views, meaning, we do not "agree to disagree."
Romans 16:17
King James Version
Now I beseech you, brethren, mark them which cause divisions and offences contrary to the doctrine which ye have learned; and avoid them.
Ephesians 4:14
King James Version
That we henceforth be no more children, tossed to and fro, and carried about with every wind of doctrine, by the sleight of men, and cunning craftiness, whereby they lie in wait to deceive;
1 Timothy 1:3
King James Version
As I besought thee to abide still at Ephesus, when I went into Macedonia, that thou mightest charge some that they teach no other doctrine,
2 Timothy 3:16
King James Version
All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:
There is a difference, I think, in reproof and correction concerning the teachings we hold to. I don't read Scripture and come to the conclusion that it's okay for anyone to believe what they want to believe. Most don't. Scripture is the given standard, and it is because there is enough common ground between so many Christians that we can without controversy proclaim certain groups cults. Because they have gone beyond issues such as what day to worship on, or what they should eat or not.
Seeing I am getting long here, I'll just say on this point, I do see it as a matter of being in agreement on doctrine. Just because I don't have a problem with those that teach you must worship on Saturday, doesn't mean I am going to acknowledge this position as anything but error. This very passage makes that clear in itself.
I agree. But our goal is to edify our brothers and sisters, is it not? Can we do that by failing to address error? And when it gets bad enough, that we restore them? How do we do that? It is my view that the learning process in our lives helps avoid it getting to a point restoration is necessary.
No argument from me. But when a duck start barking I feel we have a duty to perform. Only truth can beneficial to us. I can't help someone with omission of truth and failing to point out obvious errors.
Some might take the same view of a lot of charismatic activity. You and I view certain Catholic Doctrine to be in error, but, the ratio of people who are Catholic that actually give the doctrines we disagree with is probably pretty low.
Not to mention Catholics are as varied as Baptists. Ranging from liberal to conservative. Then, let's throw on top of that the nominal.
So, what do we do, and why do we do it?
Because we should be of one mind.
I think for most who embrace Calvinism and Arminianism, if they were to put in enough effort, both would see the errors both views hold, and maybe come to a point where, even if they do not change their view, it would be more of a sabbath day disagreement, rather than salvific, as many that are fanatical about it make it to be.
That's a mixed bag. Some of these issues involve Christian Doctrine. Clothes? A man thinking he's really a woman and wearing a dress? Could, or should such be allowed to fellowship? Political views? Should one vote for a party hell-bent on making certain issues acceptable in the general public?
And, for Pete's sake, man—there are people that preach out of the Living Bible!
Just kidding on that one.
So we should be of one mind on certain doctrines, but not on others? It's just the important ones, right? To a certain extent I would agree, certain doctrines must be more in focus, but, my point is that, while we do not necessarily excommunicate those holding to questionable doctrines, I don't think we forget that Paul states they are weak in the faith. In other words, as I said, we don't agree to disagree, but seek to edify those brothers and sisters as best we can.
For what purpose? That we should be of one mind.
I'll be honest, I am sometimes amazed how some can maintain a view in light of Scripture. How hard is it to understand that if someone feels they should worship on Saturday, Scripture demands of them that they not impose this view on others? This is just one example.
In regards to Scripture, and its interpretation, again, we know that if someone believes something to be true, true or not, it is by that standard that they will be judged.
Romans 14:14
King James Version
14 I know, and am persuaded by the Lord Jesus, that there is nothing unclean of itself: but to him that esteemeth any thing to be unclean, to him it is unclean.
Anyway, don't mind me, just trying to consider this issue in my own heart, and this is one of the best ways I know of doing that.
God bless.
