Msgr. Camille Perl's response:
Unfortunately, as you will understand, we have no way of controlling what is done with our letters by their recipients. Our letter of 27 September 2002, which was evidently cited in The Remnant and on various websites, was intended as a private communication dealing with the specific circumstances of the person who wrote to us. What was presented in the public forum is an abbreviated version of that letter which omits much of our pastoral counsel. Since a truncated form of this letter has now become public, we judge it appropriate to present the larger context of our response.
In a previous letter to the same correspondent we had already indicated the canonical status of the Society of St. Pius X which we will summarize briefly here.
1.) The priests of the Society of St. Pius X are validly ordained, but they are suspended from exercising their priestly functions. To the extent that they adhere to the schism of the late Archbishop Lefebvre, they are also excommunicated.
2.) Concretely this means that the Masses offered by these priests are valid, but illicit i.e., contrary to the law of the Church.
Points 1 and 3 in our letter of 27 September 2002 to this correspondent are accurately reported. His first question was "Can I fulfill my Sunday obligation by attending a Pius X Mass" and our response was:
"1. In the strict sense you may fulfill your Sunday obligation by attending a Mass celebrated by a priest of the Society of St. Pius X."
His second question was "Is it a sin for me to attend a Pius X Mass" and we responded stating:
"2. We have already told you that we cannot recommend your attendance at such a Mass and have explained the reason why. If your primary reason for attending were to manifest your desire to separate yourself from communion with the Roman Pontiff and those in communion with him, it would be a sin. If your intention is simply to participate in a Mass according to the 1962 Missal for the sake of devotion, this would not be a sin."
His third question was: "Is it a sin for me to contribute to the Sunday collection a Pius X Mass" to which we responded:
"3. It would seem that a modest contribution to the collection at Mass could be justified."
