bosco and Nado are rather silent about the question posed in this thread. That's quite telling.
Given the support for the two positions, as outlined above (even if we throw SH into the mix), which would appear more likely to an independent objective observer? Clearly the Church has failed to condemn as "wrong" the position that explicit faith in the Holy Trinity and Incarnation are necessary for salvation. So, by Nadonian "logic", it must be right. Be that as it may, you have the Church canonizing Doctors who taught this.
