The reader may be forgiven for wondering what on earth ‘stationary’ time is. If time moves on because it flows, it’s almost a contradiction to talk of ‘stationary’ time
One way of looking at ‘stationary’ time is to see it as a time marker that remains unchanged; i.e. points or periods of time when things happen. For instance, the Battle of Hastings happened on October 14th, 1066. This is well documented and the timing of it is unlikely to change.
We can say the same thing about the time God chose for the Word to become flesh and dwell among us. Jesus was born on earth at a particular time on a particular date. People argue as to exactly when that was, but this does not change the fact that it actually happened … or indeed when it actually happened.
