To quote the Creed “He will come again in glory to judge the living and the dead”. This is based on the testimony of the Gospels (remember the “what you did for the least of these...” lesson) and the Epistles (not to mention a certain painting in the Sistine Chapel).
All persons, living and dead, face the final judgement. For saints to go to Heaven when they die would mean that they must come out of heaven with Jesus, meet up with the wicked to face the Last Judgement and then go back into heaven. Does these mean that the wicked, having gone to hell upon their deaths, come out of hell to meet up with the saints to face the Last Judgement and then go back to hell?
The final judgment is reserved for the wicked. We will all be resurrected on the last day, but only the wicked will be judged.

Pretty much. But the saints, IIRC, will be judging with Christ, not facing judgment.
The living are anyone still alive on Earth at His return. Anyone who is alive has yet to face particular judgment.
What's not in evidence is that God will judge ALL of the dead. The living, as I stated, ALL have to be judged because none have faced the first judgment. "The dead", however, does is not supported by any similar condition. It does not imply necessarily that ALL the dead are judged. And "dead" could conceivably be referring to those that were condemned to death in the particular judgment, thus, they are already "dead" in the metaphysical sense.
John 5:24, 29
Amen, amen I say unto you, that he who heareth my word, and believeth him that sent me, hath life everlasting; and cometh not into judgment, but is passed from death to life...And they that have done good things, shall come forth unto the resurrection of life; but they that have done evil, unto the resurrection of judgment.
Revelation 20:4
And I saw seats; and they sat upon them; and judgment was given unto them; and the souls of them that were beheaded for the testimony of Jesus, and for the word of God, and who had not adored the beast nor his image, nor received his character on their foreheads, or in their hands; and they lived and reigned with Christ a thousand years.
