All names have some level of significance
to the people who bear them, though you may feel free to disagree if you have
been afflicted with parents who think calling a child Apple or Moon Unit is
a bright idea. Thankfully those folks are comparatively rare.
In ancient languages, most names were not
simply a pleasing combination of vowels and consonants chosen by moms and dads
who were stuck for a name they could agree on; they also signified something
else. The Lord renamed at least one of his disciples, and he did not do so
without purpose. The name Simon, which means “to hear”, was changed to Peter,
meaning a rock or stone. Much is said about that renaming in religious circles,
not all of it accurate, but it is certain that the change was significant both
to the Lord and to Peter. It redefined who he was.
