And the two most important paragraphs:
Factual situations may arise in which the county clerk seeks to delegate the issuance of same-sex marriage licenses due to a religious objection, but every employee also has a religious objection to participating in same-sex-marriage licensure. In that scenario, were a clerk to issue traditional marriage licenses while refusing to issue same-sex marriage licenses, it is conceivable that an applicant for a same-sex marriage license may claim a violation of the constitution. If instead, a county clerk chooses to issue no marriage licenses at all, it raises at least two questions. First, a clerk opting to issue no licenses at all may find himself or herself in tension with the requirement under state law that a clerk "shall" issue marriage licenses to conforming applications. TEX. FAM. CODE ANN.§ 2.008(a) (West 2006). A court must balance this statutory duty against the clerk's constitutional rights as well as statutory rights under the Religious Freedom Restoration Acts. Second, a court must also weigh the constitutional right of the applicant to obtain a same-sex marriage license. Such a factually specific inquiry is beyond the scope of what this opinion can answer.
In other words, there is a right for gay people to marry, even in Texas, and a clerk has a statutory duty (i.e. "shall" issue) a marriage license to anyone meeting the statutory definition; a definition that can no longer be limited to opposite sex. His opinion, when read thoroughly, makes to definitive statement that clerks do not have to issue marriage licenses.
