Q1

This book is dedicated to Q1, here called 'the Heart of the Gospel'. It is the oldest layer of the so-called Book of Q, a scholarly reconstruction of the original 'oral lore' or 'wisdom teachings' of Jesus of Nazareth in English, French and Dutch translations..

The Gospel of Mark served as model for Matthew and Luke. Besides the Gospel of Mark, both Matthew and Luke used independently from one another another source, called The Words of Jesus or Q or 'Quelle,' source. Mark did not.

The redaction of these 'wisdom words' happened in three steps : Q1, Q2 and Q3.
The oldest layer is Q1, written ca.50 CE.
