THIS SINGLE-PERSPECTIVE, ONENESS THEOLOGICAL Argument was written with the sole objective of providing understanding, clarity, revelation, as well as correction to all individuals-the Believer and non-Believer alike, with regard to an extremely misunderstood, controversial, as well as notoriously mis-taught subject matter-Angelology: The Doctrine of Angels (including, Demonology: The Doctrine of Demons). Now, in achieving this objective, I have chosen to utilize an in-depth approach of the Word of God. In short, I have provided numerous Scripture texts to aid towards complete understanding as well as clarity of this greatly debatable and grossly mis-taught Biblical subject matter. I would like to submit the following thesis statement as the Major Premise or Central Assertion of this theological thesis: Angels are Divinely-beautiful, created spiritual beings with moral judgment and Freewill. The Minor Premise or General Presupposition, then, rests solely upon the following Claim: Despite the war in Heaven, all Angels have maintained their God-given appearance as well as their heavenly-created hierarchal structure. In short, I will provide sound Biblical Evidence that all Angels are masculine as well as that they have maintained their heavenly appearance and hierarchal structure. Apostasy, then, is to be considered to hold to any other form of doctrine or belief that is contrary to this thesis. Hence, not only is any other belief that is contrary to this thesis seen as heresy, but it is to be acknowledged and accepted as false doctrine. Now, with this said, please allow me to state (for the record) that the current viewpoint of the Church (including Orthodoxy Christianity), then, may be said to be laden with numerous Scriptural inconsistencies. In other words, in doing my own Biblical study and research, I have encountered much error being taught within numerous Christian denominations (i.e., Orthodoxy Christianity) as being Biblical. With this said, contrary to standard expository writing guidelines, it is my professional opinion that this has occurred due to a lack of Biblical understanding, faulty Biblical research, spiritual blindness and deafness, improper application of hermeneutics and exegesis, as well as being guilty of not having a proper walk with God (c.f., Ephesians 3:17). This, unfortunately, has caused non-Biblical doctrinal teaching that has led to false doctrine regarding Angelology (again, including Demonology). Now, I make such a frank statement, because what is presented to you within this Single-perspective, Oneness Theological Argument, not only offers the most complete explanation of Angelology, but it provides the best Biblical Evidence as to why this Theological Argument is the most persuasive Oneness Christian Doctrinal viewpoint-it presents the most solid Biblical, contextual, hermeneutical, exegetical, and historical presentation! By the way, this Theological Thesis will be presented from a purely Apostolic Doctrinal perspective-God's perspective. As you read through this Single-perspective, Oneness Theological Argument, I ask that you momentarily suspend your doctrinal viewpoint, background, and/or tradition, then sincerely pray-seeking after The Wisdom and Counsel of God-asking God to unveil His truth, and to provide complete understanding (including clarity, if needed) of this profound subject matter. But most importantly, to reveal the spiritual insight regarding Angels (whether Heavenly or Fallen) as is plainly described throughout the Word of God.
