One True God and Perfect Generosity
In traditional spirituality One True God is meant as a being beyond a generally understood meaning of God or a pervasive essential view not literally that there is only a singular God. There are beings who are very powerful and that people refer to as God but this is not the One True God.
One must transcend ordinary values to truly understand this One True God. The best of people may do this in the sixties or later. It is very difficult to "speak" to this One True God for if this One True God entered into dualistic fixation, then a trolly catastrophic event would occur.
All beings in Heaven rally around One True God but in a sense there are some beings who are equally important as the "one" God.
Teamwork is very important in Heaven and for simplicity in teaching many people who do not have time to study and practice extensively, a reduction to an essential One True God can prove beneficial.
However, if one uses the concept that their view of God makes their religion better than another than this view can be a detriment as hostilities develop between religions rather a common understanding of good conduct.
A good discussion is Mark 12 28:34 NKJV 28 "Then one of the scribes came, and having heard them reasoning together, perceiving that He had answered them well, asked Him, “Which is the first commandment of all?
29 Jesus answered him, “The first of all the commandments is: ‘Hear, O Israel, the Lord our God, the Lord is one. 30 And you shall love the Lord your God with all your heart, with all your soul, with all your mind, and with all your strength. This is the first commandment. 31 And the second, like it, is this: ‘You shall love your neighbor as yourself.’ There is no other commandment greater than these.”
32 So the scribe said to Him, “Well said, Teacher. You have spoken the truth, for there is one God, and there is no other but He. 33 And to love Him with all the heart, with all the understanding, with all the soul, and with all the strength, and to love one’s neighbor as oneself, is more than all the whole burnt offerings and sacrifices.”
34 Now when Jesus saw that he answered wisely, He said to him, “You are not far from the kingdom of God.”"
The problem with "love your neighbor as yourself" is that people most people have little concept os a true spiritual love and do not realize the harm that they are doing to themselves and others by their actions. The phrase should read "love your neighbor as your one true self" to connect to the One True God. This is the reasons for the rewording by the scribe as these concepts are very difficult to describe just one way.
This then makes burnt offerings and sacrifices meaningless as they are. Offerings, given as Perfect Generosity is very good but this is hard to do. Sacrifices, especially animal or human are evil and people use sacrifices, that are really betrayals to justify their wrongdoings.
