Romney will deliver his speech at 10:30 a.m. ET.
WASHINGTON (CNN) - Former Massachusetts Gov. Mitt Romney says he'll serve no one religion or cause if he's elected president of the United States.
The Republican presidential hopeful will speak about religion and faith in America in an address Thursday that is being viewed as a way for him to discuss his Mormon religion.
"When I place my hand on the Bible and take the oath of office, that oath becomes my highest promise to God. If I am fortunate to become your president, I will serve no one religion, no one group, no one cause, and no one interest. A president must serve only the common cause of the people of the United States," Romney will say according to prepared remarks provided by his campaign in advance of the 10:30 a.m. ET address.
The speech comes after several recent polls have suggested that his faith may present a stumbling block in his White House quest. Romney will use the George Bush Presidential Library in College Station, Texas as a backdrop.
Earlier this week, Romney told reporters that this speech is not modeled after a similar address given 47 years ago by then-Sen. John F. Kennedy, who spoke about his Catholic faith in his successful White House run. But Romney did say he would talk about being a Mormon.
"There are some who would have a presidential candidate describe and explain his church's distinctive doctrines," Romney will say. "To do so would enable the very religious test the founders prohibited in the constitution. No candidate should become the spokesman for his faith. For if he becomes President he will need the prayers of the people of all faiths."
