When a conservative Catholic uses the term "prudential judgment", what he generally means is "I proclaim that all magisterial teachings must be accepted without question by all true Catholics. This is a magisterial teaching I disagree with, so I will cry 'prudential judgment' and pretend that I am not rejecting the magisterium". For example, Marty E disagrees with JPII's teaching on capital punishment in Evangelium Vitae, so he said it was a "prudential judgment"
