Charity covers a multitude of sins. So if H.E. advised this woman incorrectly, he did so out of charity. I will not admit that he did advise her incorrectly, but, if he did, the law of love is higher than the law of liturgical correctness. There are a few folks on this forum who are faithfully anal retentive, IMHO. For them, the letter always conquers the spirit. They will go after +Williamson in a heartbeat. They're always looking for H.E.'s soft underbelly, and striking with ferocity when they think they've found it. They're always going back and dusting off some ancient papal encyclical; or rooting out a quote from the musty pages of some Church theologian. Their behavior is highly predictable. These resident 'chupacabras' often have their fangs bared, snarling, ready to tear into pieces any idea, any principle, any sleight deviation from what they think to be the established norm, any alternative point of view, and any person holding such.
The Church is not in the business of catering to emotions and being careful not to offend anybody, being "nithe", as Bp. Williamson would say.
Telling her the truth would have been charitable. If she accepted it, it would solve her dilemma, if she didn't, well we all have free will.
But confusing her (and others!) and confirming her in her error by subjectivism is the opposite of charitable.
We are not talking about trifles. These are the principles our entire resistance to the Conciliar revolution depends on. If the New Mass is Catholic, then if its rubrics are observed in its most conservative form it cannot be evil or harm our faith, and we are substantially little more than Indultists, choosing the Traditional Mass out of preference. If it is not Catholic, then we are absolutely forbidden to attend it, except for funerals and weddings.
What I am seeing in this thread is some people telling the truth for love of the Truth, others confused, others compromising, others excusing, and others following persons instead of the Faith.
Do you love the Truth enough to correct the erring?
