Mystery: The Greek Word
The word mystery occurs 28 times in the N.T. The word mystery in not found in the O.T. The word came into the N.T. from Greek paganism. Its meaning is not something obscure or incomprehensible, but a secret imparted only to those who have been instructed. So, it is that which is unknown until it is revealed. The word is used chiefly by Paul, who knew well the world of the pagans. Paul accepted this term (mystery) to indicate the fact that, his Gospel message had been revealed to him by the risen Christ.
The word in a few passages refers to a symbol, allegory or parable, which conceals its meaning from those who look only at the literal sense, but is the medium of revelation to those who have been given the keys to its meaning or interpretation. Its most common meaning is that of a divine truth once hidden, but now revealed in the Gospel.
This is why an interpreter is needed when a pastor who is teaching the Gospel, speaks to an audience that is not familiar with his speech (tongue.) The interpreter, who is a Christian, is one who understands the Gospel, who speaks the language of the pastor, and the audience, can now explain the pastors message in the language of those in attendance, in a coherent, understandable manner.
