And in contrast to the previous two posts relaying Sim's Matthew’s Use of Mark: Did Matthew Intend to Supplement or to Replace His Primary Source? a new book on Matthew's relation to Mark by J. Andrew Doole apparently gives different answers to these questions, namely 'yes' to supplement and 'no' to replace:
J. Andrew Doole examines Matthew's sources, which the evangelist used to compile and compose his own story of Jesus. Doole suggests that Matthew was not disputing the Gospel of Mark, rather developing its tradition in a conventional manner to reinforce its authoritative position in the growing Christian movement.I'm hoping Doole is in close dialogue with Sim's 2011 NTS article. The question remains interesting and I don't believe it is easy to answer completely one way or the other.
