Latin Mass Society: Letters from the Bishop Semeraro of Albano, Italy, and then from Bishop Sarlinga of Zárate-Campana in Argentina, have declared that the lay faithful who receive the sacraments from priests and bishops of the Society of St Pius X (SSPX) are automatically excommunicated, and would need to go through a process authorised by the bishop to be readmitted to communion with the Church (i.e., not simply confession). The Latin Mass Society holds no brief to defend the position of the SSPX, which is canonically irregular, but feels it necessary to point out that these letters are not just ill-considered but have potentially very serious pastoral consequences. Full explanation is here.
