Trinity means unity of the Godhead in I John 5:7, also in John 17:11 and the three separate persons which exist in divine individuality and divine plurality (Echad) אחד are called God. Each singular state or person is called God and collectively they are spoken as one God. Hence, the word God is used either as singular or plural qualifying vocabulary. They are co-equal, co-eternal, and they co-exist before the beginning of creation.
This book prove beyond doubt all the nature and attributes of God, and established the divine precedents clearly to the clergy, laity, seminarians, and the unchurched.
