On 27 Aug 2010, the Appeals Court ruled against Utah Memorial Crosses; stating that highway crosses are unconstitutional.
Not only is it unconstitutional, the LDS Church does not endorse the symbol of the cross.
“Why should we bow down to the cross or use it as a symbol?”
~Joseph Fielding Smith – 10th LDS President, Answers to Gospel Questions 4:17~
In this same passage, he mentions wearing a cross is “in very poor taste.” (page 17)
You will not find a symbol of the cross in any LDS Church.
Mormons attempt to fit in with Christianity, while at the same time crying “foul” for patriotic (and other) reasons.
