How Can Three Be One? (1 John 5:7)
“For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one.”
(1 John 5:7)
This passage (1 John 5:7) illustrates a simple mathematical equation. We are given three variables (the Father, the Word, and the Holy Ghost). The verb “are” is used as the mathematical operation word which stands for equal to (=). It is equated as saying: These 3=1
By definition: One is singular; (as in a single person, thing, unit, kind, group, classification or category)
By definition: Three is plural; (plural is always more than one)
By definition, these two numbers are different and will never have the same meaning.
Nonetheless, the summation of this equation (3=1) can be proven true both in a mathematical and Biblical manner.
This is only achieved if these three expressions (plural – multiple ways to express God) of the equation is said to be reflective of one specific category (one being, spirit, God, etc.). In this case, the three titles listed are different expressions of this one God, not three different God personages.
The Father, the Word, and the Holy Ghost , that bear record in heaven, is = 1[God]
