Matthew, Mark and Luke report many of the same episodes, often in almost exactly the same language; but the sequence in which these episodes are reported differs greatly from one to another. In the late 19th century, it was conclusively determined that it is absolutely impossible to harmonize these chronologies — to establish a single sequence in which the alleged events would have occurred.
In the PDF file linked to here below, the center column lists the episodes reported in Luke 9—12, in the order Luke records them. The lefthand column lists those that also appear in Matthew, in the order Matthew records them. The righthand column lists those that also appear in Mark, in the order Mark records them.
