Here is one article on the religious Left supporting abortion.
As Brett Meyer pointed out, Thrivent gives matching money (from your policies) to Planned Parenthood, a major provider of abortions across America.

Thrivent gave first place to an essay from a Lutheran child who wrote that his retarded brother should have been aborted.
Nevertheless, Thrivent continues to be untouchable in Lutheran circles. When they were separate, AAL and LB used to compete to see who could give ELCA the most money. Both parts of Thrivent gave lavishly to ELCA-LCMS-WELS projects, joint evangelism and joint worship programs. Those were heady, frothy days under Mischke and Gurgle.
Here is another connection, although I cannot verify it at the moment. McGavran suggested congregations work with Planned Parenthood. McGavran, as most know, founded the Church Growth Movement. His incredibly dull book became the "Bible" for CG, and yet that "Bible" suggested jumping on the Planned Parenthood bandwagon.
Margaret Sanger, the Planned Parenthood pioneer, spoke before the KKK because they liked her ideas about getting rid of Black babies. Jesse Jackson used to be pro-life, because he was the illegitimate child of the next-door neighbor. Jesse changed his tune when he ran for president. One LCA pastor of a Black church said, "We may have more abortions than the average, but my members still know it is wrong." Thrivent does not know that much.
Margaret Sanger archives.
I served several churches that did not engage in Lutheran insurance commercialism to support their budget. They thought AAL and LB were tacky for demanding worship bulletin recognition for every pittance handed over. We survived without it.
PS - Not money, but the love of money is the root of all evil. KJV 1 Timothy 6:10 For the love of money is the root of all evil: which while some coveted after, they have erred from the faith, and pierced themselves through with many sorrows.
