Answer:

Oral gospel traditions is a theorized first stage in the formation of the written gospels as cultural information passed on from one generation to the next by word of mouth. These oral traditions included different types of stories about Jesus. For example, people told anecdotes about Jesus healing the sick and debating with his opponents. The traditions also included sayings attributed to Jesus, such as parables and teachings on various subjects which, along with other sayings, formed the oral gospel tradition.[1][2] The supposition of such traditions have been the focus of scholars such as Bart Ehrman, James Dunn, and Richard Bauckham, although each scholars vary widely on their conclusions, with Ehrman and Bauckham publicly debating on the subject.
