My conscience compels me to make this disclaimer lest God judges me partly culpable for the errors and heresy promoted on this forum... For the record I support neither Sedevacantism or the SSPX. I do not define myself as either a traditionalist or Novus Ordo Catholic, I am a Catholic period. I am simply trying my best to live a holy life in obedience and submission the Holy Father and the eternal truths as taught by Holy Mother Church.
"By withdrawing submission from the Holy Father and the faithful in communion with him, Sedevacantists are schismatic and hence automatically excommunicated from the Church under both Divine and ecclesiastical law (canon 1325, par. 2)."
In order to make this comment so nonchalantly as you did, one has to deny the dogma of EENS, for if you did believe in EENS, you would realize that you are saying that all who die as sedevacantes have gone/will go to hell.
If I truly believe as you say that "Sedevacantists are schismatic and hence automatically excommunicated from the Church", I would instead be yelling from the roof tops, warning sedevacantes that they are going to hell. For I truly believe:
Pope Eugene IV, Council of Florence, “Cantate Domino,” 1441, ex cathedra:
“The Holy Roman Church firmly believes, professes and preaches that all those who are outside the Catholic Church, not only pagans but also Jews or heretics and schismatics, cannot share in eternal life and will go into the everlasting fire
which was prepared for the devil and his angels, unless they are joined to the Church before the end of their lives; that the unity of this ecclesiastical body is of such importance that only those who abide in it do the Church’s sacraments contribute to salvation and do fasts, almsgiving and other works of piety and practices of the Christian militia productive of eternal rewards; and that nobody
can be saved, no matter how much he has given away in alms and even if he has shed blood in the name of Christ
, unless he has persevered in the bosom and unity of the Catholic Church.”
