Some commentaries call her the disciple too important to lose. Others say that there really isn't anything to the text. I say it isn't just about what it says but especially in this case it is about where it is located in the rest of the story.
Acts 9 starts out with Saul threatening the church, and then he meets Jesus on the road in the Shekinah Glory, but the followers will have nothing to do with him...until Ananias brings him into the community. The same thing happens to him in Jerusalem...until Barnabas does the same. Saul is a Pharisee too important to lose.
Then Aeneas is healed by Peter. It is not just the Pharisees that are important it is the less able bodied Israelite, as well.
Then Dorcas is healed. It is not just the Pharisees and the lame males, but also the females are too important to lose.
Acts 10 follows with Cornelius the Roman Centurion. It turns out that God is no respecter of our human divisions...even the Pagans who soil the reputation of Israel are too important to lose. Each time someone is included into the Body the Body is blessed. Perhaps God is telling us something.
So roll up your sleeves, put your mind in gear, be totally ready to receive the gift that’s coming when Jesus arrives. Don’t lazily slip back into those old grooves of evil, doing just what you feel like doing. You didn’t know any better then; you do now. As obedient children, let yourselves be pulled into a way of life shaped by God’s life, a life energetic and blazing with holiness. God said, “I am holy; you be holy. [1 Peter 1:13-16]
