Derieri-Purity (to this day)

Melascula-Faith  (to this day)

Monspeet-Reticence  (to this day)

Galand-Truth  (to this day)

Gowther-Selflessness (later on Calmadios)

Calmadios-Piety (later on Zeldris)

that leaves 4 commandments: Love(currently Esterossa), Patience, Response, and Pacifism

I think Meliodas being strongest possesed the strongest ability Love. Esterossa was young back then and most likely weak so giving him that commendement is questionable. Although i can't say if commendements might be swaped, plus Esterossa was quite shocked about the possibility of taking away some one's commendemt. So it has to be one of the 3: Patience, Response and Pacifism.
