Changing definitions

It's common in theology to take a word and change or limit its meaning. This can help if everyone knows that the meaning has been changed, but it can also cause confusion especially when speaking to people who are still justing using language in its everyday sense rather than the technical theological sense. E.g. It's common to hear Christians insist that Jesus was resurrected not resusciatated, but in everyday speech and also in etymology these two words are almost identical in meaning. Resurrect means to rise again and resusciate means to raise again, but when Christians insist that Jesus was resurrected not resusicated, they are not insisting that he experienced rising rather than raising. What they actually mean is that Jesus came back from death and will never die again but now lives an endless life, he didn't just nearly die to then be brought back to the same type of life he had before and then face death again at a later point. English-speaking preachers say that the latter is resuscitation and the former resurrection, even though that's not what these words originally meant. It is really important when talking about Jesus to explain that he did go through death and come out the other side alive never to die again, rather than just coming back to a mortal life, but that idea won't actually be communicated to people who don't know very much about Jesus if a preacher says Jesus was resurrected rather than resusciated if the preacher doesn't actually explain how he is using those words differently. Another example are the words command and decree. In everyday speech, a command is an order usually given by a person in authority and a decree is a command that has been written down in a law. But in Augustinian/Calvinist theology, those words take on different meanings when theologians talk about God's will of command and God's will of decree. In this context a command is an instruction that God has given, which could be oral only or could be written down in the form of law. It is something that God has said he wants to happen, but it is not something that God guarantees will happen and it is clear that God's laws are broken every day. However, a decree is something that God has determined definitely will happen. Unlike a command, decrees are often secret and are only made know by the fact that they actually happen. If decrees are made known, they are prophecy rather than law. And decrees can actually be in opposition to what God has commanded. E.g. It is against God's law for judges to punish the innocent and yet God decreed that Jesus would be crucified for our salvation.
