The symbolic fact passed quickly, during a long list of achievements in Carl Anderson's annual report as the leader of the Knights of Columbus.

Weeks earlier, the powerful Catholic fraternal order had donated its 700th ultrasound machine for use in crisis pregnancy centers. This was appropriate news to share during the Toronto convention, which took its biblical theme from Isaiah: "Before birth the Lord called me, from my mother’s womb he gave me my name."

"The Spanish language phrase that means 'to give birth' is 'dar a luz,' words that literally mean 'to give light' to the child," said Anderson, in his Aug. 2 text. "Our ultrasound program gives a light to the mother that enables her to see the reality and often the personality of her child in the womb."

Right now, he added, efforts to oppose abortion are linked to other public debates. For example, there are efforts to support the Little Sisters of the Poor's work with the weak and elderly, as well as their struggles against Health and Human Services mandates they believe attack religious liberty, seeking their cooperation with health-care plans supporting contraceptives, sterilizations and abortion.

This kind of work does require involvement in politics, noted Anderson, who held several posts in the Ronald Reagan administration. However, he noted that Pope Francis said: "Politics, according to the Social Doctrine of the Church, is one of the highest forms of charity, because it serves the common good."

Thus, Anderson issued a familiar challenge to his audience, which included about 100 bishops.

"We need to end the political manipulation of Catholic voters by abortion advocates," he said. "It is time to end the entanglement of Catholic people with abortion killing. … We will never succeed in building a culture of life if we continue to vote for politicians who support a culture of death."

These are fighting words in a tense year in which the GOP White House candidate has clashed with Pope Francis and Catholic bishops -- conservatives as well as progressives -- on issues linked to immigration and foreign policy.
