Indeed. HH has moved the ball and Bp. Fellay is catching it. The barkin dogs in the manger notwithstanding, the prodigal is returning and the fatted calf will be killed.
Nothing prodigal about the SSPX. The analogy I like is that of a married woman who moves out of the home, away from a husband who beats her. Doesn't mean she's divorced, doesn't mean she thinks of herself as not married, doesn't mean she doesn't recognize him as her husband. But a body's gotta do what a body's gotta do sometimes.
