(Tulsa, Ok)--It began September 24th and continues through November 2nd. Anti-abortion advocates are holding a 40 day, around the clock vigil. Tulsans are taking part in this demonstration along with fellow pro-lifers in over 100 cities. In Tulsa the vigil is taking place across the street from Reproductive Services at 6136 East 32nd Place. Abortion is one of the services offered at that clinic. Under a well lit canopy those participating in the vigil often sit and pray for an end to abortions. This national vigil is called the longest coordinated pro-life mobilization in history. Its backers claim similar campaigns have resulted in reductions of abortions taking place in the cities where the demonstrations are held. The canopy rests on land purchased by the Tulsa Roman Catholic Diocese to be used for these type of events to protest abortions just feet from a clinic. Those at the vigil say they will not confront those entering the clinic. They are willing to talk to them if they want to come to the canopy and look over the pro-life material offered.
