YOU must open yourself, your mind, to ME.

Any time I run across something by Alan Anderson or Deborah G. Whitehouse ( Who We Are ) it’s always a treat (And the fact they write, work and play together is, for me, awesome see-> PROCESS NEW THOUGHT ) .This article is no different:
Lost Threads in New Thought: Influence of Other Metaphysical (and Non-Metaphysical) Groups Carrying New Thought Off Course

“It is ironic that as other religions begin to take note of the teachings of Jesus, New Thoughters increasingly neglect them in their zeal to distance themselves from all forms of Christianity.”

So, basically, “the New Thought” became “New Thought” which replaced “Mental Science” or the “Mental Cure” without a doubt. And the “New Age”, although it may use some similar themes, is definitely not “the New Thought”.
At the turn of Y1K (Deb’s cool term), Divine Science, and Unity, along with other branches of New Thought that have since disappeared(i.e. Home of Truth, The New Church ), were in full swing. Religious Science would wait until 1927. Holmes being the last student of Hopkins and a devotee of Troward.
Horatio W. Dresser was concerned whether the New Thought churches would stand the tests of time.
Deb pointed out:

“Myrtle Fillmore's staunch Methodist background kept Unity on reasonably sound ground most of the time and preserved the bridge over which traditional Christians could cross with ease into the freedom of New Thought, but even she succumbed to pantheistic(the idea that "God" is best seen as a process of relating to the Universe) statements on occasion as she struggled to free herself from the tangles of anthropomorphism(anthropomorphism refers to the perception of a divine being or beings in human form). Fenwicke Holmes, trained as a Congregationalist minister, sought to distance himself and Ernest from pantheism, but they eventually succumbed.”

But, NOW is the ONLY time.
Emmet Fox wrote of the Impersonal Christ Truth, the Indwelling Christ (the Inner Light of the Quakers)[1]
He also wrote:

If you have a radio and you want to get the program WJZ , you tune in for WJZ. You do not expect to get that on WABC. [1]

Wayne Dyer used a similar analogy. But Trine said it first. Ralph Waldo Trine wrote “In Tune With the Infinite” [1897]
[1] Alter Your Life[1931]
People overlook the fact it was in the silence that Quimby became clairvoyant. That Quimby discovered each disease had a unique smell. That Quimby ascertained when his client made the determination to get sick, the circumstances behind it. These things people overlook. Quimby was only interested in healing the sick. Not starting a new religion. But, because of Quimby people found God.It was Quimby that first wrote of both the ego and the spiritual side of us.
Also, remember that Horatio Dresser started with the Swedenborg church and ended his years with Unitarian. His brother, J. Paul Dresser, was with the New Church.
The “New Thought” has led to the Truth.

“Man was never born and he will never die. There is no death. Death is an idea that exists in the minds of men. As long as man believes in death, he must witness and experience it. Man has no beginning and no end; he always was, just as God always was, is and shall be. “God and man are one.” “I am my Father are one.”
The man who is always quoting so-called authorities to prove the modern theories of reincarnation is himself without authority. He is still crying in the wilderness and calling other men masters and adepts. Call no man master. “Salute no man on the highway.” Salute the God within. The Kingdom of God is within, and if someone tells you it is “Lo here; lo there,” believe him not. The Kingdom of Heaven is within man.
Where is the Truth? It is within yourself.”
Rev. Joseph Murphy
THIS IS IT: The Art of Metaphysical Demonstration [1948]

“. . .it will be seen that the so-called "ego" does not return to this material world, as it never has been in it, but always is in heaven.” ~ Life Understood From A Scientific And Religious Point Of View And The Practical Method Of Destroying Sin Disease And Death (1947) by F. L. Rawson

In my view “New Age” remains a conglomerate of Theosophy, spiritualism, occult, tarot, astrology, crystals, chakras, séances, incantations, positional meditations, spiritism, pyramids, astrology etc. It has little to do with “New Thought”.

During Y1K the world didn’t change or end because of New Thought.
The world didn’t change or end because of Y2K.
And the world won’t change change or end because of 2012.
Only, YOU can change.
