Can we say "unanimously" on an issue that good moralists did not study because the issue did not exist in their time? But Fr. Scott is a good moralist in the SSPX and he, after 2005, agrees, in general or essentially, with 2005 Vatican docuмent.
Read the latest rendition of Fr. Scott's 2000 article (i.e., the new 2020 hybrid version cited above), and see if you can help me get my head around it.
The article appears to be an edited cobbling of parts of the original 2000 version (noting that the use of abortive vaccines fails the double effect test), then including and promoting the 2005 PAL docuмent which concludes double effect makes the use of abortive vaccines permissible if there is no other option.
That is to say, the article appears to suffer from internal contradiction, by cobbling together two contradictory articles (while attempting to smooth out the contradictions, like Fr. Scott's 2000 prohibition on allowing parents to use abortive vaccines in their children if required by civil authority for school enrollment).
