According the the apostles themselves they said to flee men who teach falsehoods .
You said....nor the errors within the protestant realm either . Unity with those who love and follow CHRIST
not unity with those who seduce and teach falsehoods .
Do a study on perspectives and how they influence your reality and everyone's reality from their own personal perspective.
First you have to know what is false. Odds are very good that your own personal beliefs are full of falsehoods.
There are and still is a remnant who have not bowed the knee to the error or ROME
Explain what you think would have happened if Emperor Constantine would not have befriended Christianity.
Do you think anything like the Ecumenical Councils would happened? 30,000 denominations is not a standardization, nor is it one Church.
Surely you know that there are people that think you...me...anybody are false teachers, it is all a matter of perspective.
The Catholic Church is the oldest and largest Christian Church in this world, that alone does not mean it is wrong.
A witness to an event that is a few feet from it is more reliable than a witness three miles away....that is the difference between the Catholic Church and the Protestants. Their focus and lineage from Peter is just wrong....but not far off....their lineage came from all of the Apostles with no focus no Peter. We have some of writings from the disciples of the Apostles and they lead to the Bishops that were corresponding for nearly 300 years and then attended the Roman Ecumenical Councils. The Roman Catholic Church is "the" lineage from the Apostles.
The Protestants cannot say that.....1500 years later they picked up a set of Bibles that were full of errors and tried to understand it and they are still trying to understand it. And if they keep using the King James Version they will never understand the scriptures or Christianity. Of course I am not saying the Catholics got it right either, their focus on politics and power distracted them from seeking the truth and that lead to some very bad things.....but all the Good Deeds they did and are doing gets lost in all that. And then the Protestant arrived on the scene and produced religions that see Good Deeds as irrelevant. Why would we want to follow the examples that Christ set? LOL Not to act like followers of Christ.
That why I say that as far as theology....they are all in the same boat. Now did God ever think that we would get it entirely right? No! But at least we can act like Christians and love one another. At this point we do not have to agree....how could that happen?
I prefer to remember Christ with the Bread and Wine Ritual but I still stand with the Protestants at times and eat crackers and Kool-Aid but the Catholic Host thing I have no use for, but I still fellowship and worship with both the Catholics and Protestants. Why? They are Christians and they love Christ and I love them.
And as far as Christian study....memorizing the scriptures is a good thing.....knowing what they mean is better....but learning the Spirit of Christ is the best. Because without it the scriptures are going to lead you to an empty religion that is not a reflection of Christ.
