How to use "sacred" in a sentence

Instead of honoring this sacred obligation, America has given the Negro people a bad check, a check which has come back marked "insufficient funds."

Recognition of that falsity of material wealth as the standard of success goes hand in hand with the abandonment of the false belief that public office and high political position are to be valued only by the standards of pride of place and personal profit; and there must be an end to a conduct in banking and in business which too often has given to a sacred trust the likeness of callous and selfish wrongdoing

This, I propose to offer, pledging that the larger purposes will bind upon us, bind upon us all as a sacred obligation with a unity of duty hitherto evoked only in times of armed strife.
