There are many truths to be found within the Bible , all of which we adhere to, but that which we feel best encompasses our Biblical principals as regarding our religious beliefs is this....
Man shall not live by bread alone but by every word that proceeds out of the mouth of God. Matthew 4:4
Our foundational beliefs are based on the Ten Commandments with strong emphasis on the first four commandments, which codify man's relationship to God, and the last six which represents man's relationship to his fellow man. --Matthew 22:37
God admonishes His people past and present to have no religion other than His religion.
"Hear O my people and I will admonish you! O Israel, if you will listen to Me! There shall be no foreign god among you; Nor shall you worship any foreign god. Psalms 81:8 & 9
