What are the problems with the Roman Catholic and Eastern Orthodox churches, from Protestant and other perspectives?

Not following the Bible.

Any elaborations? Thanks.

Below are two related subjects that come to mind:

– Works-based Gospel (contradicts a whole host of Scriptures, see attached).
– Related to the above: denial of eternal security of the believer - teaching that Scripture does not confer certainty about what Christ said in passages like John 5:24.

The above would be enough to constitute a problem. According to Paul in Galatians 1:8-9, and in 2 Thessalonians 3:6 and 1 Timothy 6:3-5, whoever teaches a false gospel that is contrary to the word of God, that we receive via the received text of the Bible from the apostles, should be "accursed" and should be withdrawn from.

The above situation is a result of a fundamental disagreement in authorities. The Christian who is a Bible-believer takes God's word as the ultimate authority on any topic, since it is from God, and any person speaking contrary to it is misguided or worse. In the different types of Catholicism, it isn't like this: they allow other sources and teachings to override Scripture or speak with greater authority, even though according to the Bible, man's word is of lesser authority (see 1 Peter 1:23-25, 2 Peter 1:20-21, 1 Thess. 2:13, 2 Timothy 3:16-17, 1 John 5:9 for examples).

As an example of what the Bible has to say about this, consider the Pharisees. The Pharisees were people who, during the time of the Gospel, made a similar mistake as others do now. They had taken their own manmade teachings and elevated them above the authority of scripture. That is where they got all their rules for washing different cups, pots, tables and so forth from, for example. It wasn't from the written word of God, but what they claimed was oral traditions, and really just manmade traditions. Jesus rebuked the scribes and Pharisees for this in Mark 7:5-13, which I will write into another post as it is too long to post here.

Anyway, the above is the very first thing that comes to mind on the subject you raised.

And now the passage from Mark:

"Then the Pharisees and scribes asked him, Why walk not thy disciples according to the tradition of the elders, but eat bread with unwashen hands?
He answered and said unto them, Well hath Esaias prophesied of you hypocrites, as it is written, This people honoureth me with their lips, but their heart is far from me.
Howbeit in vain do they worship me, teaching for doctrines the commandments of men.
For laying aside the commandment of God, ye hold the tradition of men, as the washing of pots and cups: and many other such like things ye do.
And he said unto them, Full well ye reject the commandment of God, that ye may keep your own tradition.
For Moses said, Honour thy father and thy mother; and, Whoso curseth father or mother, let him die the death:
But ye say, If a man shall say to his father or mother, It is Corban, that is to say, a gift, by whatsoever thou mightest be profited by me; he shall be free.
And ye suffer him no more to do ought for his father or his mother;
Making the word of God of none effect through your tradition, which ye have delivered: and many such like things do ye."
- Mark 7:5-13

Basically, there are all kinds of groups out there who would sooner elevate some manmade authority higher than the Bible, just like the Pharisees did according to this passage of Scripture. They were rebuked by Jesus Christ because they were nullifying or making the word of God "of none effect" through "their traditions which they have delivered." According to Mark chapter 7, they were rejecting the commandment of God (i.e. Scripture) in order to keep those other traditions instead.

As the Lord rightfully observes in another place in Scripture:

"For my people have committed two evils; they have forsaken me the fountain of living waters, and hewed them out cisterns, broken cisterns, that can hold no water."
- Jeremiah 2:13

There's too many reasons to go through on 4chan, as Rome is an utterly corrupt institution wholly apostate from the true religion. The best summary of this topic is in Francis Turretin's Institutes of Elenctic Theology, eighteenth topic fourteenth question "Can the church of Rome of today be called a true church of Christ? We deny against the Romanists". Unfortunately, this book is not available for free online and this chapter is too lengthy for me to transcribe. In short, Rome is corrupt in the gospel, where she denies the gratuitous imputation of the righteousness of Christ is the sole basis upon which one can be justified before God, she is corrupt in worship where she puts up images in the churches of God and teaches men to worship them and several creatures, even worshipping a piece of bread as if it were God, she is corrupt in her hierarchy wherein the pope of Rome takes the place of Christ as master of the Church, even claiming titles due only to the persons of the Holy Trinity, and she is corrupt in her sacraments by adding 5 spurious ones as well as abominating the authentic ones in doctrine and practice. "Any one of which" Turretin says "would be sufficient to make the religion intolerable and the church false, in which salvation could not be obtained".

As for the Greek churches, significant dialog with them is very much a novelty of only the last few years, and much of what is said in condemnation or praise on either side is drawn primarily from ignorance.

Catholics and Orthobros split over a host of things, one of the main issues being the filioque.

all Apostolic and Magisterial Churches conform to the Nicene Creed, declared at the first council of Nicaea.
Its about as important as the doctrine of the resurrection, if you don't believe in the creed, you're not a Christian.

Problem was, the Roman church attempted to change the creed in the 6th century. Originally, when the Creed mentions the Holy Spirit it read:
>I believe in the Holy Spirit, the Lord, the giver of life, who proceeds from the Father.
>who with the Father and the Son is adored and glorified,
>who has spoken through the prophets.

However, the Romans changed to creed to NOW read:
>I believe in the Holy Spirit, the Lord, the giver of life, who proceeds from the Father AND THE SON.
>who with the Father and the Son is adored and glorified,
>who has spoken through the prophets.

The term "and the Son" is read in Latin as "filioque" hence the name of the controversy.

This sparked a lot of controversy, not only for the change itself, but the theological implications.
Orthobros believed that it was undermining the Holy Spirit to precede both the Father and Son and disrupted the balance of the trinity.
Catholics believe the Son precedes and can send the Holy Spirit.

There were a number of other reasons for the Schism, but this one was the straw that broke the camel's back for the East.
There have been a number compromises put forth to try and reunite the Church from both sides. The main one being to change the creed from "AND the Son" to "THROUGH the Son" which would fix the Orthobros theological issues, but they're literally Orthodox. They hate change. Its in the name.

Would this even be different in Latin and Greek?

>>17802743
it wouldn't matter. Orthobros still use the original creed that doesn't even mention the Son in that line, like I said they just don't want change (which is respectable). They've also grown just more and more disdain for papal authority since the schism. Orthodox don't believe in papal infallibility like Catholics do, they don't have a Pope and don't want one.

It matters to the claim it's a possible compromise, considering it would literally be identical otherwise.

The problem isn't in one word, the problem is one side believing in an infallible pope that's basically God on earth and whenever that man becomes senile and calls for yet another crusade, millions of zogbots rush to die and loot and murder, from 1204 to 1941 and ongoing...
