Tom, it is zealous to desire the utmost respect and reverence given to the holy sacraments as you have displayed, and this zeal I share. Please do not let this develop into an unjust anger directed at those who seem to irritate you. This is not the charity of our Blessed Lord. He always retained compassion even for the most annoying and wicked of people.
I do not defend the +Thuc lineage because I go to a +Thuc ordained priest. I do not. I care about justice and truth.
The various scandals attributed to Archbishop Thuc is certainly disquieting, for sure.
However, it is not anyone's right to hold someone guilty until proven innocent; this is not how Catholic moral theology operates. God does not require this of us. The doubt has to be a positive one based in positive evidence, not a mere suspicion.
Pope Leo XIII taught that we are bound to presume the person did a Catholic rite properly if externally, everything was observed, and a Bishop does not need to possess the Catholic Faith to validly consecrate. He only needs to have been validly consecrated himself. We are not speaking of licitness, but of validity. The Church has always regarded the schismatics in the East as having valid ordinations and consecrations, despite not possessing the Catholic Faith.
Saint Francis de Sales on Rash Judgements, from an Introduction to the Devout Life:
“Oh! how displeasing to God are rash judgements! The judgements of the children of men are rash, because they are not judges one of another, and in judging they usurp the office of our Lord; they are rash, because the chief malice of sin depends on the intention and counsel of the heart, which is a hidden thing of darkness to us; they are rash, because each one has enough to do to judge himself, without undertaking to judge his neighbour…We must always do the same, Philothea, judging in favour of our neighbour, as far as is possible; and if it were possible for an action to have a hundred different aspects, we should look at it in that aspect which is the most favourable.”
