St. Augustine of Hippo wrote: "Numbers are the Universal language offered by the deity to humans as confirmation of the truth."
0 is the apex of the triangle and the first row of the Tetractys. The second row is made up of 1 and 2. The third row is made up of 3, 4 and 5. And the fourth row (the base of the triangle) is made up of 6, 7, 8 and 9.
The four dots in the fourth row are the four living creatures: "Surrounding the throne on each of its sides, were four living creatures" (Revelation 4:6) "GNT"
Numerically, the four dots or points are 6, 7, 8 and 9.
The three dots (3, 4 and 5) in the third row are the three persons of the Blessed Trinity. "Go, then, to all peoples everywhere and make them my disciples: baptise them in the name of the Father, the Son, and the Holy Spirit" (Mark 28:19) "GNT"
Blessed Trinity: Father, Son and Holy Spirit.
In Taoism, the three persons in the Blessed Trinity are called the Three Purities, the Three Pure Ones, the Three Pure Pellucid Ones, the Three Divine Teachers, the Three Pristine Ones, or the Three Clarities.
The two dots (1 and 2) in the second row are the Father and the Son. "That the Father's glory will be shown through the Son." (John 14:13) "GNT"
And the single point in the first row represents God as an indivisible unit (i.e. monotheism). "Hear, O Israel: The LORD our God, the LORD is one" (Deuteronomy 6:4) "NIV"
In Taoism, the four points in the fourth row are Si Xiang, the three points in the third row are the Taoist Trinity, the two points in the second row are Yin and Yang, and the single point in the first row is Yinyang. Yin and Yang are equal to Wuji, and Yinyang is equal to Taiji.
