Dayton and Silent Water, the short answer is, as other posters have assured you- NO. You are not guilty of the eternal sin.
We need to look at the context in which Christ spoke those words. Bear in mind what authority Christ spoke with, (even if in some cases it took a few hundred years for the Church Fathers to work out the meaning and implications of some his words); that any honest could not have failed to have been impressed by his integrity, his selfless love and goodness and his supernatural power. Those religious/political leaders resisted Truth itself(himself) with fathomless malice (even accusing Truth of being possessed by the father of lies), *for no better reason than that they feared for their own worldy status in their society. As Christ said, elsewhere, it was their father who was the Devil, the fatehr of lies.*
Incidentally, militant usually atheism-agnosticism often signifies, the loss of something you know in your heart to have been very precious, and your bitterness, until you get it back.
We also need to bear in mind how palpably wicked and worldy his opponents were - not least because all their transparently self-serving villainy was perpetrated in the name of God. Oh, yes, many were punctilious in keeping to the letter of many laws of their own devising, but in fact Christ *always* taught us that there is only *one virtue*:Love. And that all the other qualities we designate as virtues are all particular facets, kind of filtered expressions of this same one virtue. It is the fulness of the law; upon it hang all the Law and the Prophets. It is always kind, patient, etc.
Also, remember, Christ told us he came to save the world, not to condemn it. We have to be contemptuous of God's grace, no matter how hard He tries to save us, chiefly through being implacably stony-hearted towards others - particularly, the underprivileged (at least in worldly terms), bearing in mind at all times that God made the good things of this world for the benefit of all of his children. The fact that the endemically more spiritual, poor folk do not need anything like the degree of affluence that seems to drive the rich on ever and ever more remorselessly, every born Christian is under the most binding obligation to alter the political and economic structures which have been murdering the poor in our own countries and all over the world for all too long.
If that means collaborating with many, at best disoriented liberals, who condone and even promote abortion and sexual perversions of all kinds, directly, (the conservatives do so indirectly, almost certainly with massive investments in the inappropriate content industry from top to bottom), so be it - until the most basic Christian priority is respected - the right to life, food and shelter of even the poorest folk. Actually, particularly the poorest. We in the West spend more than enough on pet food to feed the thrird world. It's not rocket science that Christ should be incandescent to see people, families, having to sleeping in the streets and subways.
Also, one of the titles of the Devil is "the Accuser".
Don't be surprised if you feel occasional feelings of guilt and self-reproach. If his nibs thinks you're vulnerable in that department he'll try to work on it. Just take it with a pinch of salt. God will reassure you of his love.
Every best wish, one and all.
Paul
