When and why was the definition of the word "faithful" changed from being "full of faith (TO something or someone else) or faith-filled" to being "worthy of faith (FROM someone else), trustworthy, or constant"?

Best Answer

The modern understanding of faithful was already in place by 1706. Edward Phillips & John Kersey, The New World of Words: Or, Universal English Dictionary, sixth edition (1706) has these entries for faithful as an adjective and as a noun:

Faithful, Trusty, True, Honest, Sincere.

The Faithful, (in Divinity) Believers who are endued with Saving Faith, God's Elect or chosen People.

Unfortunately, most earlier dictionaries did not bother to define common words, and faithful is accordingly omitted from them, including the 1662 edition of Phillips's New World of English Words, which offers a definition of the given name Faith, but not of faith or faithful:

Faith, a Christian name of divers women; the signification is commonly known.

The Compact Edition of the Oxford English Dictionary (1971) lists six definitions of faithful as an adjective. Here they are (with the OED's date of first cited occurrence for each in curly brackets):

1. Of persons, their actions, etc. : Full of or or characterized by FAITH (sense 3); believing. Obs[olete]. {a 1300}

2. Firm in fidelity or allegiance to a person to whom one is bound by any tie ; constant, loyal, true. {a 1300}

3. True to one's word or professed belief; abiding by a covenant or promise, steadfast. {c 1400}

4. Of persons and their conduct: Conscientious, thorough in the fulfillment of duty. {c 1350}

5. Of persons and their actions: That may be believed or relied upon; trustworthy, veracious. Also of things: Reliable. {1340–70}

6. True to the fact or original, accurate. {1529}

It thus appears that the distinct notions of faithful as "full of faith" and as "loyal and true" already existed in 1300, and the sense of "trustworthy" was in place by 1370. Less clear is when the "full of faith" meaning fell out of use. The OED cites an example of faithful used in that sense from 1759, but (as we have seen) Phillips & Kersey (1706) does not include that definition, and neither does Thomas Dyche & William Pardon, A New General English Dictionary, third edition (1740):

FAITHFUL (A.) honest, sincere, true, just, one that may be relied or depended upon.

FAITHFUL (S.) the true professors of Christianity.
