The pope gave Obama, who last March lifted restrictions of federal funding for human embryonic stem cell research, a copy of a recent Vatican document on bio-ethics in which the Holy See explains its opposition to such practices.
"Dignitas Personae" (dignity of a person) condemns artificial fertilization and other techniques used by many couples and also says human cloning, "designer babies" and embryonic stem-cell research are immoral.
The document defends life from conception to natural death and a Vatican statement issued after the meeting said the topics discussed included "the defense and promotion of life and the right to abide by one's conscience."
The pope's private secretary told reporters after the meeting: "This reading can help the president better understand the Church's position on these issues."
"We know that this (abortion) is a crucial theme for the pope. There is no need to hide it. It (giving him the booklet) was an attempt to be clear, it was not polemical," Lombardi said.
Who knows? Maybe all those prayers for Obama's conversion of heart on the abortion issue will pay off one of these days...
