I have a few questions regarding that assertion:
What is the legal definition of personhood?
The 14th amendment to the constitution is the closest we have to a definition of personhood:
Section. 1. All persons born or naturalized in the United States and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside. No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any State deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws. (bolding mine)

Does the legal definition matter most?
In a nation of laws, yes.
Quote:
Is there any actual consensus in western society about when personhood begins?
No. The closest thing we have to a consensus is the law.
Quote:
Is the concept of personhood even scientific?
No. It's too multivariate for science to pin down at this time.
Quote:
Or is it entirely or mostly philosophical?
It's possible that neurobiology will be able to formulate something approaching a scientific definition of personhood in the next century or two.

...biology, chemistry, neurology are one thing, but philosophy and ethics go beyond that.
At this time, yes; however, philosophy and ethics that ignore reality are meaningless at best, outright destructive and evil at worst. The pope considers it 'immoral' for people to use condoms, and as a result thousands of people will catch AIDS and die horrible deaths that they could have avoided had their religious leader given them a go-ahead to protect themselves. In denying reality to promote his morality, he is producing a
real-world, factual harm.
Likewise, in claiming that an undifferentiated clump of cells should have as much state protection as the woman they reside in, there is direct,
measurable harm being inflicted on extant women and families.
