You mean, if you can't beat 'em, join 'em. Ask to have an ecumenical service instead that would include a Rabbi, an Imam, etc. Here is a little of the California statutory law on religion.
CALIFORNIA CONSTITUTION
ARTICLE 1 DECLARATION OF RIGHTS
SEC. 4. Free exercise and enjoyment of religion without
discrimination or preference are guaranteed. This liberty of
conscience does not excuse acts that are licentious or inconsistent
with the peace or safety of the State. The Legislature shall make no
law respecting an establishment of religion.
A person is not incompetent to be a witness or juror because of
his or her opinions on religious beliefs.

of the University of California shall ever be used for membership or
for any participation involving a financial payment or contribution,
on behalf of the university, or any individual employed by or
associated therewith, in any private organization whose membership
practices are discriminatory on the basis of race, creed, color, sex,
religion, or national origin. This section does not apply to any
public funds which have been paid to an individual employee or
officer of the university as salary, or to any funds which are used
directly or indirectly for the benefit of student organizations.
66292.1. The Chancellor of the California State University and the
president of each California State University campus shall have the
primary responsibility for ensuring that campus programs and
activities are free from discrimination based on ethnic group
identification, religion, age, sex, color, or physical or mental
disability.
66292.2. The President of the University of California and the
chancellor of each University of California campus shall have primary

religion, age, sex, color, or physical or mental disability.
66292.3. (a) A party to a written complaint of prohibited
discrimination may appeal the action taken by the governing board of
a community college district or the president of a campus of the
California State University, pursuant to this article, to the Board
of Governors of the California Community Colleges or the Chancellor
of the California State University, as applicable.
(b) Persons who have filed a complaint, pursuant to this chapter,
with an educational institution shall be advised by the educational
institution that civil law remedies, including, but not limited to,
injunctions, restraining orders, or other remedies or orders, may
also be available to complainants. The educational institution shall
make this information available by publication in appropriate
informational materials.
(c) Nothing in this chapter shall be construed to require an
exhaustion of the appeal to the Board of Governors of the California
Community Colleges or to the Chancellor of the California State
University pursuant to subdivision (a), before civil law remedies may
be purchased.
(d) Notwithstanding any other provision of law, a person who
alleges that he or she is a victim of discrimination may not seek
civil remedies pursuant to this section until at least 90 days have
elapsed from the filing of a discrimination complaint with the local
educational agency. The 90-day moratorium imposed by this
subdivision does not apply to injunctive relief and is applicable
only if the local educational agency has appropriately, and in a
timely manner, apprised the complainant of his or her right to file a
complaint.

You can find lots more by visiting this website:
http://www.leginfo.ca.gov/calaw.htmlChoose a code like Education or Government and search for "religion" or the topic you want to research. Some issues you might look into are whether the government is endorsing a specific religion, whether it is discriminating based on religion and/or whether it is contributing to a specific religion that discriminates based on religion by allowing it to use space without charge. You would have to know the facts.
Good luck!
