I was born and raised a strict Catholic, the church always taught that Jesus (pbuh), God and the Holy Spirit were all one in the same. Later in life, for whatever reason, I often found myself contemplating whether or not I shared the views of Christians around the world. I have recently been reading into Islam and I find that the main difference between Islam and Christianity is that Islam believes you only have 1 God, you only pray to 1 God or in other words, you should practice true monotheism. Christianity also claims to practice monotheism, in that the holy trinity is only one being (God), but here is my question if Jesus (pbuh) were God, then why would he have said on the cross "My God, Why have you forsaken me?" and why would he have prayed, and why would the devil have tempted him during his forty days in the desert with no food or water? And if Jesus was in fact not God, but the Messiah, as the bible says he is, then why would people of the Christian faith say prayers to Jesus, to me that is worshipping more than one God. Furthermore, why, if Christianity is a monotheist religion, do Catholics have the prayer "Hail Mary", and why patronize saints, and say prayers to them for small things, like say Saint Anthony for a parking spot or safe travel? Hopefully I can get some answers here, I am also posting this on a Christian site as well to see what kind of answers I will get there.
Here is the anwer to the question about what He said on the cross
He was quoting a Psalm which prophesied the persecution of the Christ.
This 1000 year old prophesy had just been fulfilled. Here is my poetic rendition of the prophesy and fulfillment(the part you reference is about half way through):
Seven Words Seven Echos:
Father forgive them, they know not what they do...
He that is without sin among you, Let him cast the first round.
And again he stooped down, And wrote upon the ground.
And they which heard it, convicted by conscience, Went out one by one, beginning at the eldest,
Even unto the last: until Jesus was left alone, And the woman was still standing in his midst.
Woman, where are your accusers? Hath no man condemned thee?
No man, Lord…. Neither do I condemn you, Go, and from your sins be free.
A gift of happy life: His law is for the people, Not the other way around.
Yea, the law is not nullified, but in repentance He cuts us free from the ropes of sin which bound.
Truly, Today You will be with me in paradise...
Master, what shall I do to inherit eternal life? What is written in the law? What there do you find?
You shall love the Lord your God With all your heart, soul, strength, and mind.
And also, Love your neighbor as yourself…. You have answered right, do this and you shall live.
And your neighbors are everywhere, whatever you give even unto the least of them, to me you also give.
The kingdom of heaven is like a tiny grain of mustard seed,
A man took it, and sowed it in his field. The mustard seed is the least of all indeed.
But when it is grown, it is the greatest among herbs, and becomes a mighty tree, the biggest and the best
So that the birds of the air may rest and lodge in the Branches thereof, make their home, their eternal nest
Mother behold thy son. Son, behold thy mother...
Blessed are your ears, for they hear and blessed are your eyes, for they see.
Truly, Many prophets and righteous men have desired to hear and see as do thee.
But many have not yet seen nor heard. Hear ye therefore the parable of the sower.
That you may find fertile soil in the hearts of men as the grower, reaper, and mower.
He that despises you, despises me and in despising me and the Father, earns reflexive shun.
For, I am the way, the truth, and the life and no one comes to the Father except by the Son.
For God so loved the world, he gave his only Son that all who believe in him should never perish
For God sent not him into the world not to condemn, but to love and save and cherish.
I thirst...
They gave him vinegar to drink mingled with gall: and when he had tasted thereof, he rejected.
They crucified him, parted his garments, and cast lots: fulfilled as the prophets had projected.
They part my garments among them, and upon my vesture they cast lots
And from the sixth until the ninth hour a darkness covers the whole land and out the sunlight blots
And at the ninth hour… My God, my God, Why hast thou forsaken me? So far from helping and hearing my words of my roaring, Art ye.
O my God, They cried unto you, and were delivered: they trusted in you, deliverance you have bourn.
But I am a reproach of men, and despised of the people. All they that see me laugh me to scorn:
They shoot out the lip, shake the head, He trusted on the Lord to be delivered: let the Lord decide his rest.
But thou art he that took me from the womb and did make me hope when I was upon my mother's breast.
I was cast upon you from the womb: you art my God from my mother's belly.
Be not far from me; for trouble is near; for there is none to apply the soothing Gilead jelly.
Many bulls have compassed me: strong bulls of Bashan have beset me round.
They gaped upon me with their mouths, as a ravening and a roaring lion, as a rabid hound.
I am poured out like water, all my bones are out of joint: my heart like wax melted and sunk to my bowels.
My strength dried up like a potsherd; I’m brought to the dust of death, my tongue cleaveth to my jowls.
Dogs compass me, the assembly of the wicked have enclosed piercing hands and feet. My blood now clots.
I see all my bones: looking back and staring at me. They part my garments and for my vesture casting lots.
But be not thou far from me, O Lord my strength, hasten to my aid. For when the afflicted cried you heard.
The meek shall be satisfied: they that seek shall praise the Lord and heart shall live for ever with his Word.
All the ends of the world shall remember and turn unto the Lord. All kindreds of the nations shall bow down
They shall worship you. For the kingdom is the Lord's. He is the governor of all nation, land, and town.
A seed shall serve him; it shall be accounted to the Lord for a generation, this grain of corn.
They shall come, and shall declare his righteousness unto a people that shall be born.
And, behold, upon his final word the veil of the temple was rent from the top to the bottom in pieces twain,
And the earth quaked, the rocks rent; open broke the grave, and a reprieve for us did he obtain.
Death and the grave have been conquered, forever vanquished:
Father, into thy hands I commend my spirit... It is finished.
