The Sign of the Cross
Richard [Rohr] invites us into a deeper experience of the Trinity through a conscious and embodied practice of the Sign of the Cross.

     First, place your right hand on your forehead and say, “In the name of the Father.” It’s funny because the Trinity is precisely that which we can’t understand and yet we begin with this attempt to understand by touching our forehead. Then make a vertical line down your body to your gut or belly, and say, “and the Son.” Jesus the Christ is the one who makes visible this eternal invisibility. That’s what we believe: that this invisible God became visible in the person of Jesus.  
     After you draw the vertical line down your body, something you can experience a little bit in your head, a little bit in your heart, and maybe mostly in your gut, then draw a horizontal line across, and say, “and the Holy Spirit.” Because the Holy Spirit is precisely that connection, that communion, that relationship, that flow of life and love that has created the whole universe. We never dared to give any personal form to the Holy Spirit because we knew it was talking about relationship itself. Instead, we have used many images—the dove, fire, wind, flowing water—all dynamic images of interaction, of relationship, of connection.  
     Let me put it this way: Whenever you feel connected, you’re in the Holy Spirit. Whenever you disconnect yourself through anger, judgment, hatred, cruelty in any form, you’re not in the Holy Spirit. You’re operating outside of that in which you were created.  
     Let the sign of the cross be a body prayer for the rest of your life. We can’t understand it, we can only allow it. We can only allow that flow, that communion, that energy, that dynamism, that vitality, that love. We’ll know when we’re there and I hope we can recognize when we’re not there. That’s how we’ll know when we’re living in the Trinity or acting as a separate you and me, standing on the side of life, instead of living it.
