Exploring the Meaning of Hupomnesis in Greek

ὑπόμνησις (Hupomnesis) means “remembrance.” It appears in Paul’s description of being prompted to recall Timothy’s faith (2 Timothy 1:5) and in Peter’s stated purpose of prompting his readers through written and spoken reminders (2 Peter 1:13; 2 Peter 3:1).

Root and Related Words

ὑπόμνησις is related to the verb ὑπομιμνήσκω (hypomimnesko), “to remind” (Strong’s G5279).

Occurrences

2 Timothy 1:5 — “having been reminded of the sincere faith that is in you, which lived first in your grandmother Lois, and your mother Eunice, and, I am persuaded, in you also.”

Here ὑπόμνησις functions as the trigger for Paul’s pastoral confidence: he speaks as one who has received a prompt that brings Timothy’s “sincere faith” back into active view. The effect of this “remembrance” is not mere recollection of a fact about Timothy, but a renewed awareness of a lived reality—faith that “lived first” in Lois and Eunice and is now recognized as present “in you also.” In the sentence’s flow, the reminder gathers multiple generations into a single line of memory: what is remembered is faith’s continuity, its dwelling across family relationships, and Paul’s resulting persuasion. The word therefore serves to connect personal recollection with public affirmation; Paul’s remembrance becomes the basis for what he is prepared to say and to rely on.

2 Peter 1:13 — “I think it right, as long as I am in this tent, to stir you up by reminding you,”

In Peter’s phrasing, ὑπόμνησις is a deliberate method for moral and mental awakening: he considers it “right” to “stir you up” through the act of reminding. The expression “as long as I am in this tent” frames the reminder within the limits of his remaining time and embodied life, so the “remembrance” is shaped as a duty carried out while he still can. The word contributes a sense of intentional reactivation: Peter’s aim is not to supply novelty but to rouse, using what his readers can recognize when brought to mind. In this scene, remembrance is presented as an instrument that produces alertness—an act that energizes rather than simply informs.

2 Peter 3:1 — “This is now, beloved, the second letter that I have written to you; and in both of them I stir up your sincere mind by reminding you,”

Here ὑπόμνησις is explicitly tied to written communication: Peter speaks of “the second letter” and says that “in both of them” he has the same aim—to “stir up your sincere mind.” The reminder is therefore not an incidental aside but a repeated strategy spanning multiple letters, addressed to “beloved” readers. The word’s contribution is to define the function of the letters: they are crafted to awaken a “sincere mind” through recollection, calling the audience back to what they already know and affirm. The repetition (“in both of them”) also portrays remembrance as something that benefits from re-voicing; the sincere mind is not merely possessed but can be “stir[red] up” again and again through reminders.

Sense and Usage

Across these three contexts, “remembrance” appears as a purposeful bringing-to-mind that yields concrete effects in relationships and communication. In 2 Timothy 1:5, the reminder results in a strengthened personal evaluation—Paul’s renewed awareness supports his persuasion about Timothy and allows him to speak of faith’s residence across generations. Remembrance there is interpersonal: something about Timothy comes freshly into focus, and that renewed focus shapes Paul’s confidence and tone.

In 2 Peter 1:13 and 3:1, remembrance is presented as a pastoral tool directed toward an audience. The goal is explicitly dynamic: “to stir you up.” The language shows that remembrance is not passive storage of information; it is a means of rousing attentiveness and moral seriousness. Peter’s reminders operate within time (“as long as I am in this tent”) and through form (“the second letter… in both of them”), so remembrance is linked with urgency and repetition: an ongoing effort to keep what is true and sincere in the foreground of the community’s mind.

These uses also show the social location of remembrance. It is not isolated introspection; it is prompted—someone is “reminded,” and someone else “remind[s] you.” The word naturally belongs to speech and writing that calls a person or group back to a settled reality. In the quoted lines, remembrance is connected with sincerity: “the sincere faith that is in you” (2 Timothy 1:5) and “your sincere mind” (2 Peter 3:1). In both cases, the reminder serves sincerity by reawakening it. Remembrance thus functions as reinforcement: it strengthens what is genuine by bringing it again to conscious recognition, whether that genuineness is located in faith or in the mind’s posture.

Imagery in Context

The passages attach remembrance to vivid, concrete frames. Paul’s reminder comes wrapped in family memory—Lois, Eunice, and Timothy—so remembrance carries the feel of a lineage recalled and affirmed (2 Timothy 1:5). Peter’s reminders are set within the image of bodily life as a “tent,” giving remembrance the urgency of a final season of service (2 Peter 1:13). And when Peter describes reminders delivered through “the second letter” and “both of them,” remembrance takes on the form of repeated written prompts designed to keep a “sincere mind” awake and active (2 Peter 3:1).
