I find it odd when I run into a group that in so many ways can see the obvious, but in other ways refuse to look.
Can you see that the holidays that are practiced today come from pagan ones from around the time the NT was supposedly put together?
Yes. So what? Christadelphians don't observe any day above another.
Is it obvious that Sunday worship was taken from Sun day worship?
Yes. So what? Christadelphians don't regard Sunday worship as mandatory. It can be done any day. Sunday happens to be the most logical time to do it, for reasons such as most people having the day off work.
Is the calender you use the same as Messiah used?
No. So what? Using the Jewish calendar would be silly.
Who removed the act of baptism underwater while having full understanding, and then replaced it with the sprinkling of newborns with no knowledge of what they do?
Christadelphians believe in and practice full water immersion baptisms. I don't think you've done your research on us particularly well.
Who approved killing your enemy and said it gains you points in heaven as long as he's a heathen, over Messiah's words, love your enemy, and turn the other cheek?
Apostate church leaders corrupted by the world. Why?
Of course the ones responsible for all this was known as the RCC, and can you tell me what fruit was produced in burning believers at the stake, or any of the other torturous deaths they brought about?
And tell me what should we know by the fruit they bare?
I'm really not sure where you're going with this.
These are the same men that are responsible for the NT you read today, a 4th century work, all known copies before this were destroyed by the order of Emperor Diocletian. So what is the proof that these text were first penned in the Greek? Nothing, not one place in scripture say I am writing to you in the Greek.
You are incorrect. There are existing New Testament fragments, manuscripts and codices in Greek from before the 4th century. The earliest date back to the mid 2nd century. You shouldn't be making these kinds of assertions when you clearly haven't done any research.
Also, why would somebody writing in Greek say "I'm writing to you in Greek"? The reader would know what language he was reading.
And many of the so called "church fathers" openly claimed that some of the books were first penned in Hebrew (Aramaic), mainly Matthew, which without a doubt reads much truer in the Aramaic, and is even poetic.
Which church fathers? Can you provide quotations? Given that almost none of them were around when the gospels were written, I need to know which ones you're referring to.
And if you knew your first century Hebrew law, you would know that in Mat 26:64 and Mar 14:62, the original event would have required Messiah to have said the name Yahweh, and not the word we find today "power"
I have no idea what you are talking about. What "first century Hebrew law" are you referring to?
I bet that you can pick any one doctrine of your choice, and list the verses that back it, and I would be able to not only match, but at least double the amount of verses that point to the importance of the name.
And I bet that the verses you listed wouldn't actually say anything of the kind. You can make the Bible mean anything you like when you approach it with pre-conceived ideas.
Why can't people see we are in the time of the great falling away, no one need be any longer forced to deny truth, they just willingly do so.
The falling away began when the apostles died and the Holy Spirit gifts ceased. It's still going on.
That Name is your mina, it was to be called upon, and shared with others, not place away in a handkerchief until his return.
I have no idea what this means either. In practical terms, what are you saying a person actually needs to do? And what difference does it make?
"But you have come to Mount Zion and to the city of the living God, the heavenly Jerusalem, to an innumerable company of angels, to the general assembly and church of the firstborn who are registered in heaven, to God the Judge of all, to the spirits of just men made perfect..." (Heb 12:22-23)
