Luke 1:2 reads (NIV emphasis mine):
... just as they were handed down to us by those who from the first were eyewitnesses and servants of the word.
Reading this recently, this struck me as unusual that Luke would refer to these first eyewitnesses as "servants of the word" rather than "servants of the Lord" or something similar. Which then got me thinking: what is "the word" to which these people were servants?
In Acts 6, the Twelve are said to give their attention to "to prayer and the ministry of the word", which would maybe seem to indicate the the word as the Scriptures. I'm not sure, though, how different "servants of the word" would be from the scribes in that case.
Famously in the Fourth Gospel, Jesus is the Word - the λόγος; but as far as I know, Luke doesn't adopt this idea.
What is "the word" that Luke has in mind such that he characterizes the first eyewitnesses as servants of this word?
