Members of the Pro-Life Action League in Chicago are planning to sing carols outside abortion clinics in the run up to Christmas to encourage pregnant women to reconsider termination.

The group actively engage in fighting against abortion, and plan to offer a message of hope by singing carols that celebrate the birth of Jesus.

"The empty manger has been a symbol of hope through the centuries, placed in the Christmas crèche in anticipation of the birth of the Christ child celebrated at Christmas," explains Eric Scheidler, Executive Director of the Action League.

"But the empty manger also represents the emptiness left behind by abortion-the emotional and spiritual vacuum where a baby once was. We don't want any woman to experience that, and that's why we'll be there to offer our message of hope."

The organisation has seen its actions have a profound effect on some women.

"We were singing 'Silent Night' outside of a Chicago abortion clinic when a young woman came out, approached one of our carollers, and said that our singing made her think about Mary and Baby Jesus and she just couldn't go through with her abortion," recalls Scheidler.

He went on to explain that the woman was directed to a nearby pregnancy centre for help.

The carollers will visit five different abortion facilities in Chicago on December 21, while another group visit clinics in Du Page County.
