Great Protestant fiction, mostly of British origin. What year was the Bible first translated into the common language of the people?
It’s pretty irrelevant: during the middle ages, translation of scripture was discouraged, the excuse used was misinterpretations, and a couple of groups were labelled as heretics when they did it.
Any prediction in the Old Testament would explain Christ establishing his Church. What New Testament predictions are you referring to?
Actually Amos’ prophecy can’t refer to Jesus establishing His church:
Amos 8:
11Behold, the days come, saith the Lord God, that I will send a famine in the land, not a famine of bread, nor a thirst for water, but of hearing the words of the Lord:
12And they shall wander from sea to sea, and from the north even to the east, they shall run to and fro to seek the word of the Lord, and shall not find it.
Given that from the time of Amos to Christ the Jewish Law still held sway, so the word of the Lord was still present and in effect, the period he speaks of must be
post Christ. Therefore, if you are right and the Catholic church has existed and remained true, recognised by God and held proper authority continually since then, this period of complete apostasy must still be to come, and all churches, Catholic included, must either fail, or none be left true and with real authority recognised by God.
Paul had quite a lot to say:
Acts 20:
29For I know this, that after my departing shall grievous wolves enter in among you, not sparing the flock.
30Also of your own selves shall men arise, speaking perverse things, to draw away disciples after them.
He knew and warned against people
from within the church congregation leading the church astray.
2 Timothy 4:
2Preach the word; be instant in season, out of season; reprove, rebuke, exhort with all longsuffering and doctrine.
3For the time will come when they will not endure sound doctrine; but after their own lusts shall they heap to themselves teachers, having itching ears;
Speaking about being diligent in preaching
to the saints, and prophesying about the future situation of the same.
2 Thessalonians:
3Let no man deceive you by any means: for that day shall not come, except there come a falling away first
‘That day’ referring to Christ’s Second Coming.
And Peter:
Peter 2:
1But there were false prophets also among the people, even as there shall be false teachers among you, who privily shall
bring in damnable heresies, even denying the Lord that bought them, and bring upon themselves swift destruction.
I’ve highlighted ‘bring in’ because it clearly prophesies that these things will not break away from the church (as many other scriptures prophesy), but be incorporated into it.
Possibly the clearest message, though, comes from John the Revelator:
Revelation 14:
6And I saw another angel fly in the midst of heaven, having the everlasting gospel to preach unto them that dwell on the earth, and to every nation, and kindred, and tongue, and people,
The everlasting gospel cannot refer to the Law of Moses, as that is not everlasting, therefore it is clear that an angel
after the time of Jesus’ mortal ministry will bring the gospel to the earth. If the gospel were already on the earth, or still here, this would be entirely unnecessary and impossible. Therefore, if the everlasting gospel needs to be returned to the earth, this is proof that whatever state any church that remains is in, it cannot be recognised by God, so He must send His gospel back to the earth.
While I agree that none of these specify any time, it is quite clear that a general apostasy is prophesied, and if it has not happened yet, then it is still to come.
Historically this is false, but how do you reason it to be true?
Historically?
Since the time Joseph Smith restored the church there has been an unbroken line of Apostles and Prophets, with a continuous stream of revelations from God, interpreting and confirming all aspects of how His kingdom is to be re-established and organised.
