invention

The word “invention” derives from the Latin inventiō, first person singular of invenīre, a combination of the preposition in and the verb venire, meaning “to come in” or “to come upon”.

Today we celebrate St. Stephen the First Martyr, the saint for whom my parish church is named. The Roman Missal, p 1139: quia ejus Inventiónem celebrámus, “for we celebrate the finding of him”. This is part of living tradition.

Now, how his bones were invented...

1) Gamaliel the Elder, Hebrew רַבַּן גַּמְלִיאֵל הַזָּקֵן, leading authority in the Sanhedrin, advises against killing the apostles, which is accepted, educated guess is he dies in AD52, saint
2) Nicodemus, Greek Νικόδημος, Pharisee, member of the Sanhedrin, appears after the Crucifixion to provide the embalming spices, assists Joseph of Arimathea in preparing the body, saint
3) Abibas, son of Gamaliel and brother of Nicodemus, saint
Sources say G, N, and A are baptized at the same time.
4) Lucian, Catholic priest
