"Once for all"
The Catholic Church specifically says Christ does not die again—his death is once for all. It would be something else if the Church were to claim he does die again, but it doesn’t make that claim. Through his intercessory ministry in heaven and through the Mass, Jesus continues to offer himself to his Father as a living sacrifice, and he does so in what the Church specifically states is "an unbloody manner"—one that does not involve a new crucifixion.
Great post, thanks!
