Tertullian quoted... i agree these three deities Father, His Spirit, and Son all are of the same substance (=nature). While God is the ultimate per 10 commandments... gods is correct here...
"These three are one substance, not one person; and it is said, 'I and my Father are one' in respect not of the singularity of number but the unity of the substance." The very names "Father" and "Son" indicate the distinction of personality. The Father is one, the Son is another, and the Spirit is another (
"dico alium esse patrem et alium filium et alium spiritum" Adv. Praxeam, ix)), and (yet in defending the unity of God, he says the Son is not other (
"alius a patre filius non est", (
Adv. Prax. 18) as a result of receiving a portion of the Father's substance.
[9] At times, speaking of the Father and the Son, Tertullian refers to "two gods".
