The sermons are nearly all attributed to people with Mendevian names, and the extent to which they align with the Acts of Iomedae is somewhat variable, but none of them outright directly contradict what Blai knows of Iomedaean theology, even when the emphasis is clearly very different. Most of them are fairly short, only a page or two; a few of them are presented with a sentence or two of context.
...Our cause is not hopeless.
Iomedae is the goddess of victory over Evil, and were our cause hopeless she would never have bestowed her gifts upon us. For it is not the way of Iomedae to grant her followers her holy blessings merely because they are courageous, merely because they are honorable, merely because they are just. She gives us her gifts not merely for who we are, but for what we will do with it, and she does not waste her blessings on those who will simply use them to perish in service of a doomed cause.
Our victory will not be easy, but nor was Her victory over the Whispering Tyrant...
...Is there a part of you that hears of his flight and wishes you could join him? A part of you that fears you will die here? Cast it aside and steel your heart! For if you perish here, the angels will welcome you into Heaven. You will have paradise with your fathers, your brothers, your brothers-in-arms. You may take up arms in Iomedae's service and continue to make war on the Abyss, or you can set down your sword forever and find peace in the Summerlands, and either way you will have paradise. As for him, he will be cast away into the torments of the Abyss. Do not envy his lot, for whatever trials you may face in this life, it cannot equal what he will face in the next one...
...and he told me that when he thought all was lost, he heard the voices of his fallen comrades whispering in his ear, telling him to have courage, and so he summoned his courage, and set upon the demons with his spear, and though he was still a novice his blows struck as strongly as a mighty warrior, for by the grace of the gods the spirits of his fellows had lingered to aid him...
...Your soul may ache to see them, knowing that they have given themselves over to the Prince of Darkness. You may wish you could reach out a hand and save them from their fate. But were it true that we would accept Chelish aid only to turn it against them, were it true that we welcomed their deserters with open arms, were it true that whenever their men stayed at our forts we sought to turn them against their Infernal masters, they would never have come to our aid to begin with. It is only because we can accept their aid without turning it into a weapon against them that they are willing to stand by our side.
We cannot hold the Worldwound by our strength alone; they are our allies, just as surely as the people of Lastwall, and one of our great advantages over the Abyss is the fact that we do not wantonly betray our allies...
...Greatest among the virtues is courage, for without courage the other virtues can never be brought to bear against any true threat. But second-greatest among the virtues is discernment...
...You may think but I am a woman, but I have lost a limb, but I am too old.
But the Goddess does not need warriors alone, and though you may not be able to serve her by taking up arms, that does not mean you cannot aid her cause, nor does it absolve you of your responsibility to do so. Anyone can ask themself how best they can serve the war against the Abyss, and then do it...
Eventually a crusader interrupts his reading to tell him that his presence is requested at the final planning meeting for the Gray Garrison.
