I just came across another open letter to the pope:
https://billditewig.wordpress.com/2017/11/02/dear-pope-francis-thanks-and-no-one-is-confused/
The writer is:
Deacon William T. Ditewig, Ph.D., 
Archdiocese of Washington, DC
Commander, USN (ret.)
Professor of Theology, and former Executive Director, USCCB Secretariat for the Diaconate and Interim Executive Director, USCCB Secretariat for Evangelization

The letter is short and should be read in its entirety, but a salient passage is this one:
"May I suggest that those who make that claim are using that language of 'confusion' to mask the truth: that they just disagree with you.
"Your writing and teaching are clear: you desire the Church to be an adult Church.  By this I do not mean a Church only FOR adults, but a mature People of God, Mystical Body of Christ and Temple of the Holy Spirit."
