There are lots of FR threads theorizing about the reasons behind Fr. Euteneuer's disappearance, but IMO everyone should start with this one:
"It is impossible to speak of a “Catholic culture” in America any longer. A whole segment of the populace who call themselves “Catholics” do not feel bound by any standard of Catholic orthodoxy or sanity. In fact, it is impossible even to speak of a Catholic culture in most parishes! At a recent “ministry faire” of a large Catholic parish in south Florida, the Respect Life ministry of the parish displayed its pro-life materials next to the table of the “social justice” committee of the same parish. Any commonality between the two ministries was simply in the space they shared. Their worldviews could not have been further apart, but they both call themselves Catholic........How can these two groups sit side-by-side in the same pews and display their ministries in the same space at the same Catholic parish? Simply because this contradiction has been tolerated for years by those in charge of our Church. In this election season neither of these two groups received any guidance about voting according to Catholic principles because, as per usual, there was silence from the pulpit on the issue. The absolute failure of our church leaders to define for us what membership in the Church means - and then to enforce it - has led to the degradation of Catholic culture and the loss of meaning for things that are sacred. When Christ and Belial are considered equal partners in the sanctuary, then nothing in the sanctuary means anything any more and no meaningful standard exists to distinguish a true Catholic from a false Catholic."
