Here is a scriptural definition (from Doctrine and Covenants section 76)
31 Thus saith the Lord concerning all those who know my power, and have been made partakers thereof, and suffered themselves through the power of the devil to be overcome, and to deny the truth and defy my power—
32 They are they who are the sons of perdition, of whom I say that it had been better for them never to have been born;
33 For they are vessels of wrath, doomed to suffer the wrath of God, with the devil and his angels in eternity;
34 Concerning whom I have said there is no forgiveness in this world nor in the world to come—
35 Having denied the Holy Spirit after having received it, and having denied the Only Begotten Son of the Father, having crucified him unto themselves and put him to an open shame.
36 These are they who shall go away into the lake of fire and brimstone, with the devil and his angels—
37 And the only ones on whom the second death shall have any power;
38 Yea, verily, the only ones who shall not be redeemed in the due time of the Lord, after the sufferings of his wrath.
39 For all the rest shall be brought forth by the resurrection of the dead, through the triumph and the glory of the Lamb, who was slain, who was in the bosom of the Father before the worlds were made.
WOW! Having denied the Holy Spirit after having received it, and having denied the Only Begotten Son of the Father, having crucified him unto themselves and put him to an open shame.
All that for denying Joseph Smith! Pretty insulting to Christians, to be accused of all that.
Normandy, there is NO evidence that the D&C is anything but a fiction from the mind of Smith and certainly it is NOT recognized as "scripture" by anyone other than the few million mormons.
