This is one question I try to avoid, altouugh when ask I say Jesus was God in the flesh or the son of God.
However I assume the Pentecostals do believe that Mary was the mother of God.
I know the Catholics like to elevate Mary, but she is not the mother of her Creator, the self-existent God. Jesus was both God and man. Mary was the mother of the man Jesus. God does not report up to His “mother”. Seems pretty blasphemous to assign an attribute like that to the Creator of everything.
All I have seen is contention against that except in certain qualified technical sense, which is not the Catholic usage. Jesus Christ is God manifest in the flesh, (1 Timothy 3:16; John 1:1,2,14) being God in nature though His real corporal, holy body that He took on (Hebrews 2:16; Phil. 2:7; 1 John 4:2,3) ) was provided for Him, (Heb. 10:5) and is not what God is by nature. (Luke 24:39)
As Jesus was God in His incarnation as He was before He was clothed with a sentient physical body, so in a certain sense it might be argued that Mary can be called the mother of God in a functional sense relative to the incarnation. But which normally denotes ontological oneness, and Mary contributed absolutely nothing to the deity of Christ.
And the Holy Spirit shows careful wording relative to the incarnation and the uncreated nature of God, clarifying that while Christ came out of Israel, yet this refers to the flesh: "Whose are the fathers, and of whom as concerning the flesh Christ came, who is over all, God blessed for ever. Amen." (Romans 9:5)
However, the RC appellation of Mother of God is not even that of a qualified technical sense, but is a exalted formal title which is preferred above the less misleading Orthodox "God-bearer," since it is part of their hyper exaltation of Mary into an omnipotent "by grace") demigoddess, paralleling Christ.
For in the the Catholic quest to almost deify Mary, it is taught by Catholics*,
As the the Son of God has a unique unique relationship with the Persons of the Trinity, so also Mary is said to have a unique relationship with all three Persons of the Trinity;
As Christ is the express image of God, and highly exalted above all under the Father, having the primary position among all creation, so Mary is declared to be the greatest saint of all, and the first of all creatures, and as having a certain affinity with the Father, with a pre-eminent resemblance which she bears to the Father;
As Christ was called the Son of God, indicating ontological oneness, so Mary is called the Mother of God (which naturally infers the same, and is not the language of Scripture, which even clarifies Israel birthed Christ "according to the flesh, God blessed for ever": Rm. 9:4,5);
As the the Son of God supernaturally, spiritually makes believing souls into children of God, Mary is said to be the mother of Christians in "supernatural and spiritual generation."
As Christ was sinless, so Mary was;
As the Lord remained a virgin, so also Mary;
As the Lord was bodily ascended into Heaven, so Mary also was;
As the Holy Spirit directs believers to be "Looking unto Jesus the author and finisher of our faith," (Hebrews 12:2) in whom believes are accounted a holy nation, (1 Pt. 2:9) so Catholicism teaches that believers are to "turn their eyes to Mary" in whom "the Church is already the 'all-holy." (CCC 829)
As the Father made Christ Lord over all things, so Mary is said to be enthroned above all creation (all other believers have to wait for their crowns) and exalted by the Lord as Queen over all things;
As Christ is given all power in heaven and in earth, so Mary is “surpassing in power all the angels and saints in Heaven.”
As Christ is given all power on Heaven and on earth, so Mary is said to have (showing some restraint) “almost unlimited power;” and showing less restraint, to be "omnipotent" (by grace);
As God the Father made His Divine Son functionally the Lord over the universe, so Mary states, "I command what I will, and introduce whom I will."
As no man comes to the Father but through the Son, so it is taught that no one can come to the Son except through Mary in Heaven;
As no one can obtain mercy, be saved/redeemed or be delivered and know the Father but through the Son, so the same is said of Mary;
As those whom God has chosen will come to Him, so it is said that if Mary wills our salvation, and then we are sure to obtain it.
As the emphasis is upon Christ as the Creator through whom God (the Father) made all things, including Mary, so it is emphasized that uniquely “to her, Jesus owes His Precious Blood,” shed for the salvation of mankind, (the logic behind which can lead back to Eve);
As Scripture declares that Christ suffered for our sins, so Mary is said to have done so also, even all the consequences of sin;
As Christ redeemed mankind (as many as truly believe) with the Father and the Spirit, so it is said of Mary that "we might rightly say she redeemed the human race together with Christ."
As Christ saves us from the condemnation and death resulting from the fault of Adam, so it is taught that man was condemned through the fault of Eve, the root of death, but that we are saved through the merits of Mary; who was the source of life for everyone.
As all things come from the Father through the Son, so Mary is made to be the dispenser of all grace; that "through her are obtained every hope, every grace, and all salvation."
As believers have confidence through Christ, so Mary is extolled as being the foundation of all the believer's confidence.
As the Lord wills all souls to be saved through Christ, so it is said that it is God's will that we obtain everything through Mary.
And as the Lord called souls to come to Him to be given life and salvation, so (in misappropriation of the words of Scripture) it is said of Mary, “He that shall find me shall find life, and shall have salvation from the Lord;” “that through her are obtained every hope, every grace, and all salvation. For this is His will, that we obtain everything through Mary.”
As Christ is the King of the saints and over all kings, (Rv. 15:3; 17:14; 19:16) so Mary is made Queen of Heaven and the greatest saint, and that “Next to God, she deserves the highest praise;”
As Christ ever liveth to make intercession for the saints, so is Mary said to be in constant intercession;
as only to God is ascribed the power and privilege of hearing prayer from all flesh, so also is Mary extolled as doing so;
as believers only address God/Christ in prayer to Heaven, including in prostration before Him, so also do Catholics pray to Mary;
as believers only pray to God to have mercy on sinners, so Catholics beseech Mary to do so.
As Catholics (adding error to error) believe Christ gave His "real" flesh and blood to be eaten, so it is emphasized that Mary gave Him this, being fashioned out of Mary's pure blood and even being “kneaded with the admixture of her virginal milk,” so that she can say, "Come and eat my bread, drink the wine I have prepared" (Prov. 9:5);
And as Christ is given many titles of honor, so Mary also is, except that she is honored by Catholics with more titles than they give to the Lord Himself! - http://peacebyjesus.witnesstoday.org/MarySC.html#ascriptions
Pentecostals are typically Protestant Arminian Evangelicals, so not sure where you got that...although there are some charismatic groups within orthodox religions now.
No; it's the Catholics.
ie: Hail Mary; mother of GOD…
I would most assuredly state that Pentecostals believe Mary to be the mother of JESUS.
The ONENESS ones don't even believe JESUS to be 'god'.
