John Macarthur Teaches that the Holy Spirit was sent by the Father and not the Father and Son
According to John Macarthur's The Master's Seminary Statement of Faith-God, the Holy Spirit was sent by the Father and not by the Father and Son. 
"We teach that the work of the Holy Spirit in this age began at Pentecost when He came from the Father as promised by Christ (John 14:16-17; 15:26) to initiate and complete the building of the Body of Christ, which is His church (1 Corinthians 12:13). 
What does the Lord Jesus Christ say?
"Nevertheless I tell you the truth; It is expedient for you that I go away: for if I go not away, the Comforter will not come unto you; but if I depart, I will send him unto you." (John 16:7)
The procession of the Holy Spirit from the Father and the Son was the major doctrinal issue that led to the "Filioque" clause, Latin for "and (from) the Son," being inserted into the Nicene Creed which in turn caused the Eastern Orthodox Church to split from the Roman Catholic Church.
The Eastern Orthodox Church believes that the Holy Spirit is feminine, which is now an issue and the subject of many New Age books such as William Dever's "Does God Have a Wife?" God's wife is called the Shekhinah, the divine feminine and Queen of Heaven, which displaces Jesus.
John Macarthur also is demoting Jesus with his teaching that He only became the Son at His incarnation and there is an Eastern Orthodox/Reformed organization called Drop the Filioque which is plotting to remove the Filioque clause from the Nicene Creed.
The Eastern Orthodox Church has many articles advocating for the removal of the Filioque, and the Evangelical churches are silent on this issue. 
"All ye beasts of the field, come to devour, yea, all ye beasts in the forest. His watchmen are blind: they are all ignorant, they are all dumb dogs, they cannot bark; sleeping, lying down, loving to slumber." (Isaiah 56: 9-10).
In denying the blood of Jesus Christ, denying He sent the Holy Spirit, and in denying His eternal Sonship, John Macarthur's beliefs are more in line with the unbelieving Jews and Unitarians than biblical Christianity.
