Luke, Gospel Of
The Gospel According to Luke (Greek: κατὰ Λουκᾶν εὐαγγέλιον) is the book traditionally placed third in the New Testament canon. It is one of four canonical gospels describing the life and teaching of Jesus. The Gospel of Luke is widely recognized as the first volume of a two volume work, the second of which is The Acts of the Apostles. The two volumes are are often referred to together as Luke-Acts.
Along with Matthew and Mark, Luke is one of the three synoptic gospels. These three gospels share similar structure, content, and wording. This has given rise to many theories as to the relationship between these gospels, the order in which they were written, and their use of sources.
If your question is about about comparisons between this book and the other synoptic gospels, rather than specific to this book, use the synoptics tag.
