I am not quite convinced Teddy had repented, since he held his pro-abort position even to his death without publicly renouncing what he had done.
All I could think of is the opportunity he had wasted to teach others before leaving this earth. The song “house of the rising sun” by Animals comes to mind ... “mother, tell your children, not to do what I have done.”
Teddy had an obligation to confess publicly because of his position, in addition to private confession, to redeem himself. He was keenly aware that doing nothing would mean he wanted others to honor his legacy as a pro-abortion catholic and for that, it cannot be an act of repentance.
The “Kennedy priest”, I wonder if the same priest had given Teddy communion time and again while an unrepentent pro-abort politician. If so, I agree this priest should shut up instead.
