Steadfast has held its ground for many centuries. Its Old English predecessor, stedefæst, combines stede (meaning "place" or "stead") and fæst (meaning "firmly fixed"). The word was first used in battle contexts to describe warriors who stood their ground, which led to its "immovable" sense. That sense gave way to the word's use as an adjective implying unswerving faith, loyalty, or devotion.
faithful implies unswerving adherence to a person or thing or to the oath or promise by which a tie was contracted.
faithful to her promise
loyal implies a firm resistance to any temptation to desert or betray.
remained loyal to the czar
constant stresses continuing firmness of emotional attachment without necessarily implying strict obedience to promises or vows.

staunch suggests fortitude and resolution in adherence and imperviousness to influences that would weaken it.
a staunch defender of free speech
steadfast implies a steady and unwavering course in love, allegiance, or conviction.
steadfast in their support
resolute implies firm determination to adhere to a cause or purpose.
