I believe NOT ONLY, but I believe Jesus is both Man(Son of God) and GOD(Father/Spirit).
Speaking in tongues is not a requirement for salvation, it is only an initial sign of receiving the Holy Spirit.
Frankly speaking I never yet speaking in tongues but I already receive the Holy Spirit.
I am only a member of Oneness Pentecostal, I am not aware such kind of doctrine forcing anyone to be healed.
What do you mean "forcing anyone to be healed"?
I was speaking about the claims of Word of Faith people that believers are entitled to healing from all physical conditions, and if they are not healed, it is because they lack faith. Is that what Oneness Pentecostals teach too? I was under the impression that is the typical belief, because I know a man from a Oneness Pentecostal family in the Philippines who believes this. Ironically, his father who is a Oneness Pentecostal just died of pneumonia, so apparnetly he didn't have this kind of faith.
Apparently you don't believe speaking in tongues is required for salvation or receipt of the Holy Spirit..good.
Concerning how Jesus is the Son of God:
The phrase "Son of God" means, primarily, that Jesus is the Messianic King of David's line.
The "Son of God" in Israelite terms means that this person represented God on earth. The human, Messianic King in a sense represented God on earth. For instance, Solomon and human kings are called "son of God" in this sense in
Secondarily, Jesus is the only-begotten Son of God, meaning that he was eternally begotten of the Father, but the primary meaning relates to the Messianic King, of which position Jesus occupies now.
2 Samuel 7:12-16 . 12 When your days are fulfilled and you lie down with your fathers, I will raise up your offspring after you, who shall come from your body, and I will establish his kingdom. 13 He shall build a house for my name, and I will establish the throne of his kingdom forever. 14 I will be to him a father, and he shall be to me a son. When he commits iniquity, I will discipline him with the rod of men, with the stripes of the sons of men, 15 but my steadfast love will not depart from him, as I took it from Saul, whom I put away from before you. 16 And your house and your kingdom shall be made sure forever before me. Your throne shall be established forever.’”
Psalms 2
1 Why do the nations rage
and the peoples plot in vain?
2 The kings of the earth set themselves,
and the rulers take counsel together,
against the Lord and against his Anointed, saying,
3 “Let us burst their bonds apart
and cast away their cords from us.”
4 He who sits in the heavens laughs;
the Lord holds them in derision.
5 Then he will speak to them in his wrath,
and terrify them in his fury, saying,
6 “As for me, I have set my King
on Zion, my holy hill.”
7 I will tell of the decree:
The Lord said to me, “You are my Son;
today I have begotten you.
8 Ask of me, and I will make the nations your heritage,
and the ends of the earth your possession.
9 You shall break them with a rod of iron
and dash them in pieces like a potter's vessel.”
10 Now therefore, O kings, be wise;
be warned, O rulers of the earth.
11 Serve the Lord with fear,
and rejoice with trembling.
12 Kiss the Son,
lest he be angry, and you perish in the way,
for his wrath is quickly kindled.
Blessed are all who take refuge in him.
The Israelite king was considered the Son of God in this sense, with the ultimate fulfillment being Jesus.
By the way, "Son of Man" also has two meanings. "Son of Man" is the Messianic figure of Daniel 7:13-14. So, Son of Man was also a Messianic term. It could also refer to his humanity. I believe it translates, roughly, to "Son of Adam". He is the second Adam, who is not disobedient, unlike our father Adam.
And, Jesus could be a "father" in this sense too as he is the corporate head of all those who are redeemed. He represents them, like Adam represents the fallen men (Romans 5:12-19). Those who are unsaved are represented by Adam and his sin, death, and condemnation. Those who are saved are represented by Jesus and his righteousness, life, and justification/vindication.
But Jesus is not the Father in the sense of the Father of the Triune God. He is the Son, not the Father. As I have said, the interpersonal language used between the Father, Son, and Holy Spirit would make the claim that there are no Persons within the Triune God to be incoherent.
