One of my favorite times of the year is the Easter season. A buddy of mine, who is now in a seminary in Conn., used to use an ancient (or at least we were told it was an ancient) way of greeting each other during the Easter season. We liked doing this greeting so much that it almost became a challenge to see who could greet the other with "Hallelujah, He is Risen!" first. Our friends thought we were a little strange.
The greeting, if you are curious, is: "Hallelujah, He Is Risen!"
The response from the person being greeted is: "Truly, He Is Risen!" or "Indeed, He is Risen!"
Though your office co-workers might not know what you are doing, what a great way to greet people and start up a conversation . . . or you might just get looked at weird. Then again, I've been told that the truth will make you weird.
