In other words, if the sspx gives you an annulment and Williamson marries you to Ernst Zundel and you go to Confession after painting a swastika on a Synagogue, your Confession will be invalid.
"SSPX confessions are invalid; so are their annulments; so are their marriages."
It is strange that Newchurch apologists now stress the importance of precise procedure for (old) sacraments where the SSPX are concerned. Have not confessions been downgraded and become some sort of 'communal washing' fest with sin excluded? Have not annulments been transformed into a thriving divorce industry?
