What did Marcion notably develop in his teachings?

Marcion notably developed a dualistic view of God in his teachings. He is recognized for his belief in two distinct deities: one who is the loving God of the New Testament, and another who is a wrathful, justice-oriented God of the Old Testament. This dualism was a pioneering aspect of his theological perspective, emphasizing a clear separation between the benevolence of the New Testament God and the severity of the Old Testament God.

This distinction led Marcion to reject the Old Testament entirely and to create his own canon of Christian scripture that focused solely on the teachings of Jesus and the Apostolic letters. His thoughts prompted considerable debate and discussion within early Christianity regarding the nature of God and the relationship between the Old and New Testaments.

Other theological views represented in the alternatives present different interpretations of God which do not align with Marcion's dualistic perspective. For example, the concept of a singular God focuses on the unity of God without the dualistic division that Marcion proposed. Similarly, Trinitarianism emphasizes the coexistence of Father, Son, and Holy Spirit within one essence, which contrasts sharply with Marcion's framework. Universalism posits that all people will ultimately be saved, which ties into a very different understanding of
