It's incredible that some people (except Cantarella) on this thread fallaciously leave open the possibility for a God-less partaker of Hollywood filth, Robin Williams, who died by ѕυιcιdє, which is a mortal sin, to make it to Heaven, but the Orthodox, including men and women in monasteries and convents, are "damned to perdition".
Repentance at death is
always a possibility, but, of course, what is possible is not necessarily probable; it is wrong to presume, which is what the Novus Ordo is notorious for doing. In any case, the following remains absolutely true:
1) Individuals, under no circuмstances whatsoever, should take their own life, that is, commit ѕυιcιdє. Such is always gravely sinful, and at a minimum, gravely risks eternal damnation, from which there is no escape.
2) The Orthodox, as with every other human being without exception, should convert to Catholicism, the One True Faith. Such is the infallible teaching of the Catholic Church:
Moreover, since subjection to the Roman pontiff is necessary for salvation for all Christ's faithful, as we are taught by the testimony of both sacred scripture and the holy fathers, and as is declared by the constitution of pope Boniface VIII of happy memory, also our predecessor, which begins Unam sanctam, we therefore, with the approval of the present sacred council, for the salvation of the souls of the same faithful, for the supreme authority of the Roman pontiff and of this holy see, and for the unity and power of the church, his spouse, renew and give our approval to that constitution, but without prejudice to the declaration of pope Clement V of holy memory, which begins Meruit .

The above should remove any and all doubt that it is an infallible teaching of the Catholic Church that "submission to the Roman Pontiff" is necessarily for salvation, for all human beings, whoever they may be.
