Why this is a "Catholic's" not a "Christian's" guide to biotechnology

This morning I got a great e-mail from a reader who was troubled by the fact that this blog is a "Catholic's" guide to biotechnology and not simply a "Christian's" guide to biotechnology.  I realized this excellent comment was an opportunity to explain that this is not meant to be exclusionary.  I blog for all, from atheists to Baptists, and am often most excited by my non-Catholic readers.  That being said, this blog will remain distinctly Catholic.  Here is (essentially) my reply as to why:

Dear Reader,

Thank-you for you comments.  You are not the first to suggest that what I discuss is first Christian and second Catholic.  Overall, you are correct.  But I cling to the denomination for a very important reason. It has nothing to do with being exclusionary.  There are two Church teachings that I use to guide all of my decisions regarding the ethics of biotechnology.  The first we undoubtedly share: that human life at all stages has dignity and deserves respect and should be protected.

The second is a principle that is just as important in this arena as the first but is not necessarily a tenant of Protestant denominations: to create a human being outside of the act of love between a husband and wife is immoral.  This speaks specifically to IVF and another reproductive technologies like cloning that are in our future that "order up" human life in a dish.

It is this second principle is distinctly Catholic.  It is this teaching that makes me hesitant to simply call my site Christian since many Christian denominations have accepted IVF as a good.  I am not willing to concede that it is.  And without the second principle, my arguments loose their internal consistency.

Basically, I am for "truth in advertising".  I am Catholic and I use Catholic teaching to guide my writing. 

I hope that clarifies my reasoning for you.  That being said I will tell you that I write for a very wide audience.  In fact some of my most prized readers are liberal atheists.  So all are welcome.  My goal is to present a much maligned but much needed view into the Brave New World we live in.

As I am not nearly as versed in the teachings of other Christian denominations, I would love to know other's thoughts.  Let me know what you think.
