“Faith” and “trust” in the ancient Greek were the same word: pistis. Somewhere since that time, the meaning bifurcated into distinct nuances. Perhaps the world became more complicated, or maybe just the liberals were in charge.
A “faith account” and a “good trust estimate” demonstrate how the words are not interchangeable. They could mark the difference between real estate and fictional property.
Furthermore, Saint
Augustine of Hippo, whose name graces our oldest city, helped promote the idea
that faith is the basis of knowledge. Thus
“faith” has a connotation as a starting point.
A good faith estimate is subject to change. “Trust” is a fiduciary relationship, and
implies a more stable resonance.
