"The Purple Book of Systematic Theology - Volume 1 - The Foundation" (Cleber Pinto Coimbra and Anderson Dias) challenges "Current Theology," proposing a new organization and perspectives on faith.Volume 1 addresses five central themes:1. God: Criticizes the doctrine of the Trinity as non-biblical and influenced by the Council of Nicaea (325 AD) and Constantine. It defends the oneness of God and Jesus as His visible Image.2. Sin: Redefines Original Sin as an "intrinsic imbalance" in the human condition, present in Adam and even in Jesus (though overcome by Him). The "old man" is crucified with Christ, not an accidental nature.3. Death: Is seen as an essential transition. Paradise was transferred to Heaven after Christ's resurrection. It introduces the Tribunal of Christ for believers (judgment of works, not salvation) and the "Outer Darkness" as discipline.4. Church: Its origin is heavenly, in Christ (analogous to Eve from Adam), distinct from Israel. It reconciles Predestination and Free Will, viewing the Church as a "heavenly embassy."5. Communion: Argues that it is not an ordinance for the Church. Paul's rebuke to the Corinthians aimed to correct idolatry and disunity, not to institute a ritual. "Do this in remembrance of me" referred to the period of Jesus' death, not a continuous practice.The work seeks a deeper, contextualized understanding of the Scriptures, using clear language to challenge traditional dogmas and lead the reader to a more intimate faith with God.
