I've read this four times - are you saying "paying into pastor's abortions"????
Surely I'm reading this wrong and maybe you've clarified it by now.
I just don't know what to say....
The Presbyterian Cchurch(USA) medical benefits plan is mandatory for all installed pastors. Abortion for any reason, at any time during pregnancy, is a covered service of the denomination's plan.
The coverage includes partial birth abortion; it includes abortion by means of chemicals, such as RU-486; it includes abortions for minor dependent daughters with no requirement for parental notification; it includes no requirement for medical necessity.
General Assembly Council Executive Director John Detterick, when he was President of the Board of Pensions--the PC(USA) entity that designs and administers the plan--said, "The simple fact is that the medical plan pays for elective abortions as ordinary medical payment."
The fact of abortion coverage affects not only the pastors, their families, and other denominational staff who use it, but also those who pay the dues for the plan. The tithes and offerings of contributing church members are used to pay the dues.
