Let me offer a third possibility.
The middle LSJ on Perseus also offers for LOGIKA the (apparently
more nearly primitive) meaning of having to do with speech.
Also, for service or act of worship (if I remember correctly,
the Greek is LEITOURGIA) I like "priestly service" in this context
-- generally, it seems to mean any kind of "public service".
So my own preference is for something like
your declarative priestly service
your priestly service of declaration
The idea being, it seems to me, that presenting our bodies as
a living sacrifice is supposed to serve that kind of function
-- i.e., an ongoing sacrificial presentation of the LOGOS, which
I generally interpret as meaning a "declaration" or "statement".
