testifying of plausibility of a few sentences

[vil]

Dear teachers,

Would you be kind enough to give me your considered opinion concerning the plausibility of the sentences below?

My girlfriend is a person with a facile disposition.

Her sweet disposition was the greatest recommendation to be my wife

She is a woman of a gentle disposition.

She may have since been short with you or otherwise seems to have an unpleasant disposition when you walk in the room.

James Bond is a real diplomat with a bland disposition and Sean is the perfect counterpart on the screen.

Such a verse clearly suggests that our Lord Jesus was equipped with a buoyant disposition.

Hence there arises a natural dialectic, that is, a disposition to argue against these strict laws of duty... and if possible, to make them more compatible with our wishes and inclinations...

I have the disposition of the land in question.

We are men of like disposition.

Their disposition ruffled perceptibly lately.

My personal opinion:

My girlfriend is a person with a facile disposition. Unnatural.
Her sweet disposition was the greatest recommendation to be my wife. Old-fashioned
She is a woman of a gentle disposition.Rather formal and/or old-fashioned.
She may have (since) been short with you or otherwise seemsed to have an unpleasant disposition when you walk in the room. I don't think you'd notice someone's unpleasant disposition when you walk into a room.
James Bond is a real diplomat with a bland disposition and Sean is the perfect counterpart on the screen.This does not sound natural to me
Such a verse clearly suggests that our Lord Jesus was equipped with a buoyant disposition. Unnatural

Hence there arises a natural dialectic, that is, a disposition to argue against these strict laws of duty... and if possible, to make them more compatible with our wishes and inclinations... This is a rather formal sentence, and seems to work.

I have the disposition of the land in question. Fine, in a formal, legalistic text.
We are men of like disposition. Old-fashioned.
Their disposition ruffled perceptibly lately. Not really.
