I would like you to answer the following questions:
1- Is all of the Bible GOD's Divine Revelations?
2- Did the Prophets of GOD really write the Bible of today?
3- Is the Bible perfect?
4- Did man indeed corrupt the Bible?
5- Is the Bible of today reliable?
If your answer is no to most of or all of the above questions except for #4, then allow me to say that your faith has serious problems!
The Gospel of Mark:
"Although there is no direct internal evidence of authorship, it was the unanimous testimony of the early church that this Gospel was written by John Mark. (From the NIV Bible Commentary, page 1488)"
So, in reality, we don't really know whether Mark was the sole author of this Gospel or not. And since The New Testament wasn't even documented on paper until 150-300 years (depending on what Christian you talk to) after Jesus, then how are we to know for sure that the current "Gospel of Mark" wasn't written by some pro of Mark?
Further regarding this Gospel, we read the following commentary about Mark 16:9-20:
"Serious doubts exists as to whether these verses belong to the Gospel of Mark. They are absent from important early manuscripts and display certain peculiarities of vocabulary, style and theological content that are unlike the rest of Mark. His Gospel probably ended at 16:8, or its original ending has been lost. (From the NIV Bible Foot Notes, page 1528)"
This quote raises a very serious issue here. First of all, as we've seen above in the first quote, we have no evidence that proves that John Mark was the sole author of this so called "Gospel". Second of all, we see that this Gospel has some serious problems/suspicions in it
The quote "or its original ending has been lost" proves that what we call today "Gospels" were not written by their original authors such as Mark, John, Matthew, etc... It proves that the Gospel had been tampered with by man. Let alone considering it as the True Living Words of GOD Almighty.
If John Mark wasn't the one who wrote Mark 16:9-20, then who did? And how can you prove the ownership of the other person? Let alone proving that it was GOD Almighty's Revelation. And as we saw in the first quote above, we don't even know that John Mark was indeed the one who wrote the so called "Gospel of Mark".
To say the least in our case here, we now have enough evidence to discard the entire Gospel of Mark from the Bible, because you can't take bits and pieces of it and say some of it belongs to him and some of it doesn't! Let alone considering the entire corrupted Gospel as the True Living Word of GOD Almighty, which is a complete blasphemy.
The Gospel of Luke:
There is a serious forgery about Jesus' "resurrection on the third day" claiming that it was foretold in the OT when it wasn't! Let us look at Luke 24:44-48 from the NIV Bible:
Luke 24
44 He said to them, "This is what I told you while I was still with you: Everything must be fulfilled that is written about me in the Law of Moses, the Prophets and the Psalms."
45 Then he opened their minds so they could understand the Scriptures.
46 He told them, "This is what is written: The Christ will suffer and rise from the dead on the third day,
47 and repentance and forgiveness of sins will be preached in his name to all nations, beginning at Jerusalem.
48 You are witnesses of these things.
Luke 24:44-48 says that it is written in the Law of Moses (i.e., the Torah) that Jesus will die and resurrect on the third day. Where in the entire Old Testament (not just in the 5 books of Moses that make up the Law of Moses or the Torah) do you have that?! Show me one Old Testament verse that prophesized about Jesus' third day resurrection?
"The author's name does not appear in the book, but much unmistakable evidence points to Luke. (From the NIV Bible Commentary, page 1529)"
Again, we don't know for sure whether it was Luke or not who wrote the "Gospel of Luke" since his name doesn't appear in the Book. The Gospel itself seems to be a compromising one to the Word of GOD. Let us look at the following:
"Therefore, since I myself have carefully investigated everything from the beginning, it seemed good also to me to write an orderly account for you, most excellent Theophilus, (Luke 1:3)"
Few problems with this Gospel from the quote above:
1- The author was not inspired, and knew for sure that he was not inspired by GOD Almighty to write the Book since he didn't mention about any divine inspiration, and he said "...since I myself have carefully investigated everything from the beginning..." Where do we see GOD's inspiration in this?
2- The author wrote it for the purpose of "his most excellent Theophilus." Since when we compromise GOD Almighty and document His Holy Words for the purpose of other higher (in rank) human beings?
Luke 1:3
Therefore, since I myself have carefully investigated everything from the beginning, it seemed good also to me to write an orderly account for you, most excellent Theophilus,
The following is from the Catholic Encyclopedia:

If Theophilus existed in either the 2nd or the 4th centuries then how could the writer of this gospel be the same Luke who is supposed to be with Jesus in the 1st century.
Maybe he lived to about 200 years..
