From the article:
The Arlington Diocese, which includes nearly a half-million Catholics across northern and eastern Virginia, is one of a small but growing number that are starting to demand fidelity oaths. The oaths reflect a churchwide push in recent years to revive orthodoxy that has sharply divided Catholics.
Such oaths are not new for priests or nuns but extend now in some places to people like volunteer Sunday school teachers as well as workers at Catholic hospitals and parish offices.

The Arlington “profession of faith” asks teachers to commit to “believe everything” the bishops characterize as divinely revealed, and Arlington’s top doctrine official said it would include things like the bishops’ recent campaign against a White House mandate that most employers offer contraception coverage. Critics consider the mandate a violation of religious freedom.

“The church is foremost a communion, not a building,” said the Rev. Paul deLadurantaye, Arlington’s head of education and liturgy. “And the church’s teaching is meant to be a service, not to coerce or oppress. . . . This is just to say the church is a reliable guide, more reliable in these matters than what I read elsewhere. There’s something more transcendent than just my own judgment.”
On liturgical matters, the diocese prohibited, via Bishops Welsh, Keating and the current Bishop Paul Loverde, the traditional Latin Mass from 1969 until 2006, when two such Masses were permitted (along with female altar boys at the novus ordo granted the same day). After the motu proprio Summorum Pontificum, 13 of the diocese's 68 parishes, plus the chapel of Christendom College, offer the traditional Latin Mass (about one of every five). This is a diocese where conservative and traditional-leaning priests are clearly having an influence on where things are headed.
UPDATE: Here is the profession of faith.
