Background information:
Greco-Roman era: This term means to put one in mind, to remind, to bring to one’s mind, to mention (suggest), to call to mind, and to have been observed. The Latin prefix sub- means up from below and –venire means to come. Homer’s Odyssey 1.32 states “The goddess, flashing-eyed Athena, departed and flying upward as a bird; and in his heart she put strength and courage and made him think of his father even more than a foretime.” Sophocles’ Philoctetes 1170 states “Again, again, you have recalled the old agony to my thoughts—kindest though you are of all who have visited before!” Aeschylus’ Persians 329 states “Syemesis, also the governor of the Cilicians, foremost observed in courage, he whose prowess did the most harm, found there a glorious death.”
Old Testament: This term means to remember, to keep in remembrance, to make a memorial, and to mark (as to be recognized). This term is used both in an active and passive sense. The notion of recalling a memory is likened to piercing or piercing the memory. Remembering or recalling an event often means memorializing it. This sometimes involves making a memorial offering. A recorder (historian) was often tasked with recording events as they occurred. The sayings of the wise are like goads; like fixed spikes are the collected sayings given by one shepherd (Ecc.12:11). God remembered Noah and all the animals, wild and tame, that were with him in the ark (Gen.8:1). For the avenger of bloodshed remembers, does not forget the cry of the afflicted (Psa.9:13). I will make your name renowned through all generations (Psa.45:18). Every time they think of Judah, they shall stand in dread because of the plan the Lord of host has in mind for them (Isa.19:17). Then the master of the palace, Eliakim, Shebna the scribe, and the chancellor Joah came to Hezekiah and reported to him the words of the commander (Isa.36:11).
New Testament: This term, used in an active and passive sense, means to remember, to remind, and to draw attention to. In 3 Jn.10 the writer draws attention to what that person is doing, spreading evil nonsense. Peter is reminded by Jesus’ words, that he will deny Him three times. The Holy Spirit reminds others of what Jesus has taught and told. Peter reminds others to be a witness to the truth. Jude reminds others that the Lord had saved the people in Egypt. Paul tells Timothy to remind others of these things and to confront the false teachers.
Scripture:
“And the Lord turned and looked at Peter; and Peter remembered the word of the Lord, who he had said to him, ‘Before the cock crows today, you will deny Me three times.” Lk.22:61
Upon hearing the cock’s crew, Peter is reminded how he had betrayed Jesus three times.
“Therefore, I will always remind you of these things, even though you already know them and are established in the truth you have.” 2Pet.1:12
Peter reminds others to always to testify to the truth.
“Therefore, if I come, I will draw attention to what he is doing, spreading evil nonsense about us. And not content with that, he will not receive the brothers, hindering those who wish to do so and expelling them from the church.” 3Jn.10
John may come and confront Demetrius who is confrontational, ambitious, and hostile.
Conclusion:
Souvenir
It was interesting to learn about the Latin prefix of this term meaning to recall or remember. The Latin “sub” (up from below) means bringing up memories. One can also cause others to bring up memories. Another more nuanced use means being known by others.
In the Old Testament, the act of remembrance was a very highly held value in remembering an event. The Passover was a very important event that was remembered and reenacted.
In the New Testament, Jesus continues this practice of remembrance. Jesus instructs His disciples to “do this in remembrance of Me” (again and again…). Reminding can be used for instruction (truth) and shaming.
Catholic perspective: The Mass celebrates the Eucharist in which the original one true bloody sacrifice at Calvary is re-presented. The offered bread and wine are changed in the Body and Blood of Jesus. This practice is repeated at every Mass.
Just a reminder, a souvenir is simply something (trinket, key chain, gift, etc.) which is a reminder (or recollection) of a past event or experience. 
Au revoir!
