Here I want to deal with Mushtaq’s final two question before asking some of my own. Again, his questions are in italic.
Your these man made words [Trinity] are totally Unbiblical and create confusion “Blessed Jesus is the Son within the Trinity”. From Adam to Moses and Blessed Jesus, not even a single Prophet taught his nation these words to clarify concept of God.
I have also heard these words first time from you. Bible uses words “Son of God”, Bible doesn’t use words “Son within God”. After the invention of Trinity in Council of 4th century, The God has become Triune God and “Son of God” has become “Son of Triune God”. You know Triune God has three persons, so Son of Triune God means Son of three persons? Son of Two persons? Or Son of one person? This man made confusion resulted by man made Triune God can be resolved if you use any of the following options:
Option 1: Son of Triune God means Son of father, Son of Son (Grand Son of God) and Son of Holy Spirit (Holy Spirit is 2nd father in Trinity).
Option 2: Son of Triune God means Son of Father only, Father is equivalent to Triune God. Father and Son are one and same. So when second member of Triune God crucified and died, Father was also crucified and died.
Option 3: Son of Triune God means Son of first part of Triune God. Father is first part of Triune God, as already demonstrated above.
Option 4: Son of Triune God means ….. to be told by you, if you disagree with all above three options.
Al Quran: Surah/Chapter 005 – Al-Mâ’idah. Verse 72-74
Those who say, “God is the Messiah, son of Mary,” have defied God. The Messiah himself said; “Children of Israel, worship God, my Lord and your Lord.” If anyone associates others with God, God will forbid him from the Garden, and Hell will be his home. No one will help such evildoers. Those people who say that God is the third of three are defying [the truth]: there is only One God. If they persist in what they are saying, a painful punishment will afflict those of them who persist. Why do they not turn to God and ask his forgiveness, when God is most forgiving, most merciful?
Certainly the word ‘Trinity’ is not found in Scripture, but there are so many places where the OT and Jesus describe God in the plural, that one can see where the Fathers drew their inspiration from.
The OT further specifies the nature of divine plurality by identifying the three persons of the Godhead. These three persons are all distinguished from each other, and yet, in various ways, are identified as God: the Father (e.g. Deuteronomy 32:6; Isaiah 63:16, 64:8, Malachi 2:10); the person variously designated as the Messenger of the LORD (Heb. Malakh Yahweh), Word, or Son of God (e.g. Genesis 16:7-14, 21:17-18, 22:9-18, 28:10-22 (cf. Genesis 31:11-13), 32:22-32 (cf. Hosea 12:3-4); Exodus 3, 13:21 (cf. 14:19), 23:20-22; Numbers 22:21-41; Judges 2:1-5, 6:7-24, 13:3-22, 2 Samuel 24:16; Psalm 2, 110:1, Isaiah 7:14, 9:6, 63:9; Jeremiah 23:5-6; Proverbs 30:4; Zechariah 1:10-11, 12:8; Malachi 3:1); and the Holy Spirit or Spirit of God (e.g. Nehemiah 9:20; Job 26:13, 33:4; Psalm 104:30, 106:32-33, 139:1-24, 143:10; 2 Samuel 23:1-3; Isaiah 11:2, 40:13; Ezekiel 11:5; Micah 2:7).
To say that writing of God as Trinity is ‘unbiblical’ is not supported by these passages. Indeed, given them, it is hard to see how Islam can support the claim that God is a single person.
As the Son was the Word Incarnate, fully-human and fully-divine, it is quite wrong to say that when the Incarnate Word died, the Godhead died; the Incarnate Word died and rose again; the Father and the Spirit were not Incarnate and were not crucified; nor was the Divinity of the Word dead.
I am presenting this part for information /reference only to show that God is not author of confusion and all Christian world is united in belief of ONE God taught by Prophets & Blessed Jesus; but Christian world was divided and still is divided due to man made confusion of Trinity:-
Nontrinitarianism (or antitrinitarianism) refers to Christian belief systems which reject the doctrine of the Trinity as not having scriptural origin. Nontrinitarian views differ widely on the nature of God, Blessed Jesus, and the Holy Spirit. Various nontrinitarian views, such as Adoptionism, Monarchianism and Arianism existed prior to the formal definition of the Trinity doctrine in 325, 360, and 431 AD, at the Councils of Nicaea, Constantinople, and phesus. Nontrinitarianism was later renewed in the Gnosticism of the Cathars in the 11th through 13th centuries, in the Age of Enlightenment of the 18th century, and in some groups arising during the Second Great Awakening of the 19th century.
Modern nontrinitarian groups or denominations include Christadelphians, Christian Scientists, The Church of Blessed Jesus Christ of Latter-day Saints, Dawn Bible Students, Friends General Conference, Iglesia ni Cristo, Jehovah’s Witnesses, Living Church of God, Oneness Pentecostals, Members Church of God International, Unitarian Universalist Christians and the United Church of God.
Islam, which considers Blessed Jesus a prophet but not divine, teaches the absolute indivisibility of a supremely sovereign and transcendent god, and is distinctly antitrinitarian as several verses of the Koran teach that the doctrine of Trinity is blasphemous.
Al Quran: Surah/Chapter 112 – Al-Ikhlas. Verse 1-4.
Say: He is Allah, the One and Only; Allah, the Eternal, Absolute; He begetteth not, nor is He begotten; And there is none like unto Him.
All the heresies you mention are just that – heresies. They are not orthodox, and they are not of the Spirit of Truth. Islamic belief is incompatible with the teachings of the prophets as listed above, and with the Fathers of the Church. It rejects the self-revelation of Jesus in preference for false witness.
Let me conclude with some teachings of the possibly the greatest of the early Fathers:
Origen (185-254). Alexandrian theologian.
“If anyone would say that the Word of God or the Wisdom of God had a beginning, let him beware lest he direct his impiety rather against the unbegotten Father, since he denies that he was always Father, and that he has always begotten the Word, and that he always had wisdom in all previous times or ages or whatever can be imagined in priority… There can be no more ancient title of almighty God than that of Father, and it is through the Son that he is Father” (De Princ. 1.2.; PG 11.132).
“For if [the Holy Spirit were not eternally as He is, and had received knowledge at some time and then became the Holy Spirit] this were the case, the Holy Spirit would never be reckoned in the unity of the Trinity, i.e., along with the unchangeable Father and His Son, unless He had always been the Holy Spirit.” (Alexander Roberts and James Donaldson, eds., The Ante-Nicene Fathers, Grand Rapids: Eerdmans, 1975 rpt., Vol. 4, p. 253, de Principiis, 1.111.4)
“Moreover, nothing in the Trinity can be called greater or less, since the fountain of divinity alone contains all things by His word and reason, and by the Spirit of His mouth sanctifies all things which are worthy of sanctification…” (Roberts and Donaldson, Ante-Nicene Fathers, Vol. 4, p. 255, de Principii., I. iii. 7)
The point here, Mushtaq, is that you are proceeding not according to the Christian method of divining truth, but according to the mistaken view that the Bible can be read apart from the tradition of which it is a part. This you may see if you answer three questions of my own.
1. Did Jesus say He was writing a book or founding a Church?
2. By what means was the nature of the Bible revealed to us?
3. What was the teaching of the disciples of the Apostles on the nature of God?
