SOME OF THE PRINCIPAL DOCTRINES, &c.
"We beleive in God the Eternal Father, and in His Son Jesus Christ, and in the Holy Ghost."
We believe that God is a distinct parsonage, having body and parts like man, for we read that God said " Let us make man in our own image, after our likeness."
We believe the personage of God, can no more than the person of man, be in two separate and distinct places at the self same instant of time.
We believe the personage of God is filled with the Holy Ghost, and this Holy Ghost or Spirit of God, is diffused through all space, and by this spirit, God is every where present beholding the works of his hands.
"We believe that men will be punished for their own sins, and not for Adam's transgression."
We believe Christ atoned for the original sin of Adam, therefore little children that die, without one exception, will be saved.
