While "these doubts have [NOT YET] been clarified", some in the pro-life community seem to be throwing caution to the wind. Dianne N. Irving, Ph.D. has long been a voice of reason, saying: Not so fast! Just 10 days ago, Dr. Irving asked: "Are these iPS cells just 'embryo-like', or are they - at least sometimes - really single- or multiple-cell early human 'embryos', or even human totipotent cells that have the natural capacity to revert back to new whole human embryos?" <www.lifeissues.net/writers/irv/irv_138ips_notadultstemcell.html>.
In four short months since Dignitas Personae, Ms. Vadas acknowledged (in our phone conversation) that there has been no Church teaching to abrogate Dignitas Personae's caution. I believe it is the responsibility of (arch)diocesan Respect Life offices to MUCH better disseminate Dignitas Personae, including its caution.
