Good evening and shalom
I came across this just now:

Marcionism was a Christian Gnostic sect and dualistic belief system that originated in Rome around 144 AD with the teachings of Marcion of Sinope. Marcion was a theologian and evangelist who was the son of a bishop of Sinope in Pontus. Marcionism flourished from the 2nd to 7th century AD and included some parts of the New Testament, but denied others:
Christ's humanity: Marcion believed that Jesus was a divine spirit who appeared to humans in human form, but did not take on a fleshly body
The Old Testament: Marcion rejected the Old Testament as the work of the creator God
Jewish biblical traditions: Marcion rejected attempts to harmonize Jewish biblical traditions with Christian ones
Marcion also edited his own versions of the biblical books, accepting as authentic all of the Pauline Letters and the Gospel According to Luke. The established church considered the Marcionites to be the most dangerous of the gnostics, and popes such as St. Pius I and St. Anicetus fought to stop the spread of the movement.
