It has always been made clear that several and most of what Christians believe in such as the crucifixion of a savior, the unique son of God, are all just borrowed doctrines and terms from other pagan religions before Christianity. The evidence is there for all to see, however so, Christians always like to ignore this fact and simply act like they don't know about it. Since Christians will not accept the fact that most of their beliefs come from paganism, doubting the information they read since they do not trust it, I shall say fine, let us play that game.
What I will do in this article is simple quote a Christian church Father and a Saint, this Saint happens to be Justin Martyr, The fact that this man has been given the title of Saint by Christians tells us that he is a very high and respected figure within Christianity.
Here is some information regarding Justin Martyr incase there are some Christians out there saying Justin Martyr is a nobody:
Christian apologist, born at Flavia Neapolis, about A.D. 100, converted to Christianity about A.D. 130, taught and defended the Christian religion in Asia Minor and at Rome, where he suffered martyrdom about the year 165. Two "Apologies" bearing his name and his "Dialogue with the Jew Tryphon" have come down to us. Leo XIII had a Mass and an Office composed in his honour and set his feast for 14 April.

All his work alongside many other Church Fathers and Saints can be found on this link:
http://www.newadvent.org/fathers/

It is from one of his works that I shall be quoting from; the piece that I quote from is called ?The First Apology'.
With all this said, I shall now quote the relevant information from this Saint of Christianity:

CHAPTER XXI -- ANALOGIES TO THE HISTORY OF CHRIST.
And when we say also that the Word, who is the first-birth of God, was produced without sexual union, and that He, Jesus Christ, our Teacher, was crucified and died, and rose again, and ascended into heaven, we propound NOTHING DIFFERENT from WHAT YOU BELIEVE regarding those whom you esteem sons of Jupiter. For you know how many sons your esteemed writers ascribed to Jupiter: Mercury, the interpreting word and teacher of all; AEsculapius, who, though he was a great physician, was struck by a thunderbolt, and so ascended to heaven; and Bacchus too, after he had been torn limb from limb; and Hercules, when he had committed himself to the flames to escape his toils; and the sons of Leda, and Dioscuri; and Perseus, son of Danae; and Bellerophon, who, though sprung from mortals, rose to heaven on the horse Pegasus. For what shall I say of Ariadne, and those who, like her, have been declared to be set among the stars? And what of the emperors who die among yourselves, whom you deem worthy of deification, and in whose behalf you produce some one who swears he has seen the burning Caesar rise to heaven from the funeral pyre? And what kind of deeds are recorded of each of these reputed sons of Jupiter, it is needless to tell to those who already know. (Justin Martyrs First Apology: http://www.newadvent.org/fathers/0126.htm)

Notice what this man is saying, he is telling the Roman rulers that what the Christians believe in is nothing different than what the Roman pagans believe in, that Jupiter who is one of their gods also had sons, making them sons of god. Justin then goes on to mention other beliefs of these Roman pagans of people ascending into heaven just like Jesus did etc.
So if this is not enough prove that the Christian belief system is the same as the pagan beliefs then I don't know what is! This Christian saint is saying it in plane words that what the Christians BELIEVE IN IS NOTHING DIFFERENT THAN WHAT THE ROMAN PAGANS BELIEVE IN, how much more clearly do you want it to be?!

This all proves that the Christian faith of Paul was simply another branch of paganism that popped out, the only difference is that Paul claimed it was from the true God and other forms of paganism was wrong. Paul borrowed all his beliefs from pagan religions that were around him, and centered it all on Jesus, and then he had the audacity to say the other pagans are wrong when he plagiarized their belief! What makes this all the more worst for the Christian faith is that Paul also destroyed the Jewish law given by God to Moses!
So Paul destroys God's true law given to Moses, making it into nothing, and replaces it by pagan beliefs claiming that this is the true way! He has managed to fool up to a billion people into believing they believe in a true faith of God, when in fact they believe in paganism and that the true law from God is actually made into nothing and thrown away! The Jews living at the time of Paul were not dumb, they knew that Paul was destroying the Torah, which is exactly why they did not like him, however so the pagans loved Paul so his form of pagan Christianity succeeded and this is what you have today.
But no need to worry, Islam has come to abolish ALL forms of paganism including this one created by the anti-Christ Paul.
And Allah Knows Best
