levels of moral obligations?

[Guest Aluigi]

does anyone know if i can use Aquinas to say that there are different levels of moral obligations? does anyone know of any other philosophers I can use to say this? it's for a Lincoln Douglas Debate

the resolution is "when called upon by one's government, individuals are morally obligated to risk their lives for their country"

i want to argue that this resolution merely states a moral obligation, not whether it is above or below any other moral obligation. for this to effectively turn around the opposition, i need philosophers who admit that even when a moral obligation exists, there could be a higher moral obligation that supersedes it. i don't know why i'm thinkin aquinas, i just think he might have somethin.

i had always assumed that my understanding of degrees of moral obligation came from aquinas...........from the summa i'm sure. you may want to start there.

well i was alright simply explaining that different levels of moral obligations exist i didn't even use a philosopher and it was still a good point.
