This letter may be used to give to those who will be Baptized in Water to send to their friends and family as an invitation.
Dear
I wanted to take a moment to send you this note to let you know that I'm taking a deeper (literally) step in my faith as I will be baptized in water on (DATE)!
I'm very excited about this, and wanted to be sure to send this invitation to you as you are someone I would love to have there with me to celebrate and witness this very special moment in my Christian walk.
