Things that make me go HMMMMMMM -- vague references to the Bible

The archbishop of San Francisco of the Roman Catholic Church has banned California representative Nancy Pelosi from taking Holy Communion because of her support and promotion of abortion.  The Scriptures are clear on this: "You shall nor murder" (Exodus 20:13; Deuteronomy 5:17, et al).  

The editorial staff of the San Francisco Examiner is demanding that the Pope remove the archbishop from office.  They have no business making such a demand, but it is not surprising that they would.  What is surprising, however, is Nancy Pelosi's response to being banned.  She invoked the Bible to defend her stance on abortion.  

Well, my curiosity is piqued.  What Scripture will defend her position?

From this article (Nancy Pelosi defends abortion stance on MSNBC, hits back at archbishop by referencing the Bible) Pelosi is referenced (a quotation would have been better) as saying, "the Gospel of Matthew was the 'agenda' of the Church, a position that she claimed is rejected by many who side with them on the termination of pregnancies."  In addition, Pelosi said (this time she is quoted): "This decision taking us to privacy and precedent is very dangerous in the lives of so many American people and again not consistent with the Gospel of Matthew."

HMMMMM....  "The Gospel of Matthew...."?  What, exactly, in the Gospel of Matthew is she referring to?  Chapter and verse would be helpful, especially if she holds the Church (in particular, the archbishop) in contempt.  If the Church needs correction on the topic of abortion based on the Gospel of Matthew, a clear verse from the Gospel of Matthew ought to do the trick.  Where is it?  What is it?  Having read the Gospel of Matthew many times, I don't know what she is talking about or what this "agenda" in Matthew's Gospel is.

Now, in an effort to be fair to Mrs. Pelosi, maybe she did cite a verse and the reporters neglected to put it in the article.  Editors pick and choose what they deem worth printing, so a quotation from the Bible may be considered unsavory or offensive by them.  But I doubt it.  I suspect that the reporters and Pelosi herself would find great delight in showing up the archbishop with a clear, Scriptural rebuke of his position.

But it is not just the position of the archbishop or "the Church."  It is what the word of the Lord says.  Mrs. Pelosi clearly rejects that, and she was unable to provide a verse that explains why.
