Wow, some of the stuff in there is extremely Modernist; Bergoglio could have written it.
This:
The chaplain need have no hesitation in anointing schismatics and even heretics, when they are dying unconscious, if the circuмstances make it possible to do this without causing scandal or hostility. For there is a good probability that such persons have sufficient intention to receive this Sacrament, at least in their general desire to make use of the means established by Christ for their salvation.
Why might this cause "scandal" if it's OK, Father? Oh, because the faithful have more faith regarding Catholic ecclesiology that you do, that the Sacraments are not permitted to those who are not members of the Church? Because this would inspire religious indifferentism in the faithful?
We see right here the same Modernist thinking that Father Feeney battled against, and this type of attitude here gave rise to Vatican II. We're all shocked when we see the Modernists today say that schismatics can receive the Sacraments, but it's OK when the same thing was written in 1948?
