It talked about how Protestants ministers were using it to understand biblical basis for the Mass.
I've been to an Anglican mass in England (to quite a few actually before the penny dropped!) and their practises and beliefs are similar to ours.
I prefer not to use the term "Protestant" for our brothers and sisters in Christ but as per their separate faith foundations like Lutherans, Anglicans, Presbyterians, Pentecostals, Baptists, Methodists etc.
