In his May 20, 2002, five-page letter to the Synodical President, Synodical
  officials in the South Wisconsin, North Wisconsin, and Michigan Districts, and
  officers of Redeemer Lutheran Church, St, Clair Shores Michigan, Doctor Waldo
  Werning continues to attack the fundamental doctrines of the Trinity. The
  Athanasian Creed confesses: "Neither confounding the Persons nor dividing
  the Substance." The Creed also states: "Which faith except everyone
  do keep whole and undefiled, without doubt he shall perish
  everlastingly."
  Werning Argues that Jesus is not God on the Cross
  In the following quotations from his May 20, 2002 letter, Werning claims
  that he will not be trapped into saying that Jesus is God on the Cross or that
  in Christ, God died on the cross. He claims it is false doctrine to say that
  every person of the Trinity is all of God apart from whom there is no other
  God and yet there is only one God. He claims that Jesus died in the flesh, but
  that God did not die on the Cross in Christ. He claims that Jesus is part of
  God, and not all of God. He divides the substance of God and makes Jesus less
  than God.
  Werning writes in part on May 20, 2002:
  "In your attempt to trap me by the use of your fabricated statements
  to explain the mystery of the Trinity, you have become guilty of false
  doctrine, and since you are adamant and refuse to listen or to understand what
  the Athanasian Creed (Unity and Substance of the Trinity) and the Apostle's
  Creed (Three Persons in one Godhead, three Articles) you have become guilty of
  false doctrine and heresy, as seen in the Dec. 27 and Feb. 26
  Transcripts."
  "John 3:16 tells that God (the Father) sent His Son Jesus to the
  Cross, but He did not send Himself or the Holy Spirit to the Cross."
  "Matt. 1:21 does not say that Mary will give birth to a son who is God
  the Father or is God the Holy Spirit, but a son who is Jesus."
  ". . . , you have confused the entire issue of the Son of God taking
  upon Himself human flesh in the Son of Man, who died, not His eternal Spirit,
  for Jesus said, 'Father into Your hands I commit my Spirit.'"
  "1Peter 3:18-19: '(Christ) was put to death in the body but was made
  alive by the Spirit, through whom also He went and preached to the spirits in
  prison.' Your philosophical statement that all of God died on the Cross, not
  one third of god, not dividing God, literally not only denies the Personhood
  of the Godhead (Apostle's Creed), but denies the humanity of Jesus, and
  insists on making it appear that the Father and the Holy Spirit also become
  human and took human flesh. At the same time, your misinterpretation leads to
  the conclusion that the eternal God was dead and in a grave for three
  days."
  Doctor Waldo Werning defends his teachings about the Trinity in his book
  "Health and Healing for the LCMS." The book was sent to every 2001
  LCMS Convention delegate. "Jesus First," the political action group
  most responsible for the election of President Gerald Kieschnick, endorses
  Werning's book. Former Chairman of the Council of Presidents, John Heins, is
  Werning's witness in Dispute Resolution and the South Wisconsin District
  President and other officers have published signed letters defending Werning
  's teaching on the Trinity.
  Luther and Chemnitz on the Unity and Persons of the Trinity
  The following quotations from Luther and Chemnitz
  teach that every person of the Trinity is all of God in His own Person, yet,
  there is only one God. No Person of the Trinity can be just a part of God.
  Jesus is God on the Cross. In Jesus, God suffered, died, was buried, and rose
  from the dead.
  Chemnitz writes:
  "That is to say, Scripture bears witness that the three persons and
  the entire Trinity are the one true God, and that each person is perfectly and
  in all respects that one true God." (Martin Chemnitz, "Loci
  Theologici" CPH 1989, Page 74)
  "For with respect to us the three persons are at the same time and
  each individually the one, true, undivided God, so that when the dove
  descended, one can correctly say that this is the one true God and beyond Him
  there is no other God, as it says in John 14:9, 'He who sees Me, sees My
  Father also. ' And again in v. 10, 'I am in the Father, and the Father in Me.
  On this basis we can understand how the church directs its prayers sometimes
  to the Father, sometimes to the Son, and sometimes to the Holy Spirit. For it
  believes and confesses in its prayers not only that the three persons are the
  one true God, but that each person is not just a part of that one divine
  essence but rather is the entire divine essence, that is, the one true God,
  than whom there is no other God.'" (Martin Chemnitz, "Loci
  Theologici" CPH Page 76)
  Luther writes:
  "You may say very correctly of the dove: That is God, and there is no
  God beyond that one. And yet it would be incorrect for you to say: That is God
  the Father; that is God the Son. You must say: That is God the Holy Spirit.
  (Luther's Works 15:304)
  "You may say very correctly of this voice: That is God, and there is
  no God beyond that. But it would be incorrect to say: That is God the Son or
  God the Holy Spirit. No, you must say: That is God the Father." (Luther's
  Works 15:305)
  "You can say very correctly of the man [Jesus Christ] that is God, and
  there is no other God beside Him." (Luther's Works 15:305)
  "However, it is also correct to say that God died for us, for the Son
  is God, and there is no other God but only more Persons in the same
  Godhead." (Luther's Works 15:310)
  "You have heard earlier that the Father is the God and Father of us
  all, that the Son is the God and Father of us all, that the Holy Spirit is the
  God and Father of us all, and that, for all of that, not more than one God is
  our Father. For the essence is undivided, therefore no matter which Person you
  may mention, you have named the one true God in three Persons, since each
  Person is the same, one, perfect God." (Luther's Works 15:310-11)
  ". . . unless He became a man like us, so that it could be said: 'God
  died' 'God's passion,' 'God's blood,' 'God's death.' For in His nature God
  cannot die; but now that God and man are united in one person, it is correctly
  called God's death, when the man dies who is one thing or one person with
  God." (Lutheran Confessions, Formula of Concord, Article VIII, Par 44,
  Concordia Triglotta pages 1029-1030)
  The Loss of the Trinity is the Loss of the Christian Faith and Salvation
  God cannot be divided or He is not God. Each Person of the Trinity is all
  of God apart from whom there is no God and yet there is only one God.
  The proponents of the Church Growth Movement such as Dr. Waldo Werning,
  "Jesus First," and members of the COP have become so comfortable in
  making up their own worship they are now bold to claim the right to make up
  their own God.
  Romans 10:9 states: "That if thou shalt confess with thy mouth the
  Lord Jesus, and shalt believe in thine heart that God hath raised him from the
  dead, thou shalt be saved." Belief in this verse must not be interpreted
  to mean that a proper understanding of the Trinity is not necessary for
  salvation.
  According to the Athanasian Creed, the gates of hell await any who divided
  or confuse the substance of God. If Jesus and every person of the Trinity are
  not all of God in His Person, then what part of God is Jesus? Werning refuses
  to answer the question. Werning also refuses to confess that Jesus is God, not
  a part of God, on the Cross.
  Indeed, in his most recent letter, he refuses to confess that Jesus is God.
  Just like Arius and the Unitarians, Werning prefers to call Jesus, "the
  Son of God." This is a true statement if Werning means that "the Son
  of God" is God. However, in Werning's teaching, He will not describe
  Jesus as God on the Cross.
  The most troubling part of Werning's false doctrine is that it has such
  broad based support among so many LCMS officials and pastors. Their attitude
  is that loving Jesus is more important than confessing the correct doctrine of
  the Trinity. Indeed, stewardship may have become more important than the
  Athanasian Creed.
  Never in the history of the Synod have LCMS clergy challenged the official
  doctrine of the Trinity with such impunity as Werning and his allies are now
  doing.
