As Salamu 'Alaykum Coming from a Pentecostal Heritage, I have always sought to understand the concept of The Holy Spirit. I would greatly appreciate clarification and correction to this post in this thread. My research indicates that prior to the turn of the twentieth century (I do apologize for not knowing what that would be by the lunar calendar which is probably a more correct method of observing the flow of time.) the study of The Holy Spirit was practically none existent in Modern Theology. However, with the commencement of The Pentecostal Movement and it's Charismatic element, Pneumatology became a primary sub-division of Theology. This post will hopefully present the subject in a way that will make it possible for my Islamic brothers and sisters to know my understanding of The Holy Spirit and if I have any misunderstandings to help me see them. I hope to present what the current English Version of The Bible (Old and New Testaments) has to say about this area of Theology and also present some of the extraneous Historical Data available. I am not able to state with much verifiable certainty what the early Christian Church has to say about The Holy Spirit. I do contend that the early followers of Yeshua the Messiah did not consider The Holy Spirit to be a second or third person of the trinity. In fact, it is a known historical fact that the concept of a trinity was a much later conceptualization of God. The original followers of all the prophets held firmly to the literal meaning of Deuteronomy 6:4 which states Deu 6:4 שׁמע ישׂראל יהוה אלהינו יהוה אחד׃*! and is translated Deu 6:4 HEAR, O ISRAEL: THE LORD OUR GOD, THE LORD IS ONE. All the Prophets of Allah (PBUT) from Adam (PBUH) to Moses (PBUH) and Yeshua The Messiah (PBUH) to Muhammad (Salla Allahu "alayh Wa Sallem) taught Monotheism in the strictest sense and meaning of the word in any language. Al-Baqara And when there cometh unto them a scripture from Allah, confirming that in their possession - though before that they were asking for a signal triumph over those who disbelieved - and when there cometh unto them that which they know (to be the truth) they disbelieve therein. The curse of Allah is on disbelievers. (89) (MY APOLOGIES FOR USING A TRANSLATION HERE; UNFORTUNATELY, THE WORD PROCESSOR THAT I AM CURRENTLY USING SHUTS OFF WHEN EVER I ATTEMPT TO PASTE ARABIC.) "La ilaha il Allah" Al-Baqara And they say: Allah hath taken unto Himself a son. Be He glorified! Nay, but whatsoever is in the heavens and the earth is His. All are subservient unto Him. (116) Al-Baqara Allah! There is no God save Him, the Alive, the Eternal. Neither slumber nor sleep overtaketh Him. Unto Him belongeth whatsoever is in the heavens and whatsoever is in the earth. Who is he that intercedeth with Him save by His leave? He knoweth that which is in front of them and that which is behind them, while they encompass nothing of His knowledge save what He will. His throne includeth the heavens and the earth, and He is never weary of preserving them. He is the Sublime, the Tremendous. (255) Al-E-Imran He hath revealed unto thee (Muhammad) the Scripture with truth, confirming that which was (revealed) before it, even as He revealed the Torah and the Gospel. (3) Al-E-Imran Lo! This verily is the true narrative. There is no God save Allah, and lo! Allah he verily, is the Mighty, the Wise. (62) And if they turn away, then lo! Allah is Aware of (who are) the corrupters. (63) Say: O People of the Scripture! Come to an agreement between us and you: that we shall worship none but Allah, and that we shall ascribe no partner unto Him, and that none of us shall take others for lords beside Allah. And if they turn away, then say: Bear witness that we are they who have surrendered (unto Him). (64) Al-Maeda And when Allah saith: O Jesus, son of Mary! Didst thou say unto mankind: Take me and my mother for two gods beside Allah? he saith: Be glorified! It was not mine to utter that to which I had no right. If I had ever said it, then Thou wouldst have known it. Thou knowest what is in my mind, and I know not what is in Thy Mind. Lo! Thou, only Thou, art the Knower of Things Hidden? (116) An-Nahl Allah hath said: Choose not two Gods. There is only One God. So of Me, Me only, be in awe. (51) Al-Mumenoon Allah hath not chosen any son, nor is there any God along with Him; else would each God have assuredly championed that which he created, and some of them would assuredly have overcome others. Glorified be Allah above all that they allege. (91) Al-Maeda They surely disbelieve who say: Lo! Allah is the third of three; when there is no God save the One God. If they desist not from so saying a painful doom will fall on those of them who disbelieve. (73) So, we know that any concept that makes Allah a partner, a biological father, or a third of God is false because the Hebrew Scriptures, "Greek Scriptures" (As far as they have been preserved correctly) and Al Qur'an all state "La ilaha il Allah" (I am posting this much because it is frustrating to have your writing disappear because your computer shuts off before finishing. I, Insha Allah, will get to the point of this thread in the immediate future. Alhamdulliah.
