There's been a lot of buzz about the "receiving" of a report that would propose alternative names for the Trinity such as*:
1. Rainbow, Ark and Dove
2. Speaker, Word and Breath
3. Overflowing Font, Living Water and Flowing River
4. Compassionate Mother, Beloved Child and Life-Giving Womb
Without studying the issue or the report, I am inclined to agree with Rev. Lovelady which states in the Layman article " that the Trinity paper "suffers from a confusion about the name of God." He (Lovelady) said there is a difference between a name and a metaphor." It seems to me that God may express his being/character in a metaphor, but may wish to be addressed as something else, in this case I presume it should only be "Father, Son, and Holy Spirit".
