holy ? church

About five years or so ago, wording in the Catholic mass changed. One of those changes was a response:

"May the Lord accept the sacrifice at your hands for the praise and glory of his name for our good and the good of all his Church." (before)

"May the Lord accept the sacrifice at your hands for the praise and glory of his name for our good and the good of all his holy Church." (after)

One word was inserted: "holy".

Since those changes were made, I've wondered why. Why would the church add one word to a response that seems totally adequate as it stands? More importantly, why would the church add this one word to this response at a time when child sexual abuse by priests and higher-ups covering it up has become public?

In Mark 10:18 and Luke 18:19 Jesus says that only God is holy.

 "holy" church? I don't think so.
