Are Fr’s Copenhagen and Wolf saying that the remote material cooperation argument is erroneous and inadmissible, because, since one who would take the vaccine implicitly wills to benefit from that ongoing theft/sin, and therefore this cooperation is actually direct and formal (not remote or material)?
I don’t recall either using the term “formal,” but that seems to be the implication of their argument.
This is a very strong argument, and I think the burden now shifts to those who are defending the permissibility of receiving abortive vaccines in reliance upon remote material cooperation in evil to explain how/why the ongoing theft of cells is not direct and formal cooperation.
