Eternal sin
Thomas Aquinas lists, or has responded to, six sins that supposedly go against the Holy Spirit:
Thomas Aquinas explains that the unforgivability of blasphemy against the Holy Spirit means that it removes the entrance to these means of salvation; however, it cannot hinder God in taking away this obstacle by way of a miracle.
Vanity
In many religions, vanity, in its modern sense, is considered a form of self-idolatry in which one likens oneself to the greatness of God for the sake of one's own image, and thereby becomes separated and perhaps in time divorced from the Divine grace of God. In Christian teachings, "vanity" is an example of pride, one of the seven deadly sins. Also, in the Bahai Faith, Baha'u'llah uses the term 'vain imaginings'.
