Always distinguish your terms, especially as they are related to the Church…Do you know the differences in terms: Holy See, Vatican and the Catholic Church??? They are not the same…our Catholic faith has an order, you know. I was told once I was too fussy. Really?
Father Jerabek, a student at the Pontifical Atheneum of the Holy Cross (Rome) doing work in canon law is also a priest of the Diocese of Birmingham (AL), briefly identifies the differences in terms.
