bkniceley, the point of my post was to say that while we are indeed united in the basics as you put it, everybody who does believe in the basics is automatically united in the basics, and so there is no point in Jesus praying for us to be united in that way! If this is what he meant when he was praying for unity, it would make more sense if he was to pray for people to believe in the basics. Therefore he must have been praying for some other kind of unity, namely organisational unity (forgive my spelling, I’m an Australian).
Now about Romans 14. You said,
I think there are certain differences like these that every different church sees with another and because of this they choose to split and break apart and therefore not be united organizationaly
But in today’s Catholic Church, people have disagreements like this all the time! But do they “choose to split and break apart…”, no, they don’t! They have disagreements, yet they remain in unity with each other, just as in Romans 14. Also, the main difference that the Protestant Churches see with the Catholic Church is in the authority of the Catholic Church, but that is another story.
Now, I do not think that Paul was talking about “big things” in Romans 14; for as he says in 1 Corinthians 1: “Now I beseech you, brethren, through the name of our Lord Jesus Christ, that ye all speak the same thing and that there be no divisions among you”. So what was he talking about (in Romans 14)? I think the answer is matters of conscience, or “small things”. In terms of today, the answer would be “things that haven’t been formally defined by the Catholic church”. And so if the Catholic church says that salvation is by faith, hope and works, then you should not disagree with one another about this. But if the Catholic church hasn’t formally said that eating pork is bad, then if one Catholic decides that it is bad, and another Catholic decides that it isn’t bad (as per their own consciences), then they should not judge one another in these matters.
