There was no suspense Thursday morning at Council Chambers.

There was, however, plenty of drama.

Not the kind of drama that comes from an uncertain outcome. I’m talking about a drama that makes the air heavy with anticipation, with the rare sense that history is about to unfold before your eyes.

On Thursday morning, Rosie Castro became a member of the San Antonio City Council.

That fact had been predetermined a day earlier when council members put aside their own recent precedent and came out of the applicant-interview process for the District 7 interim appointment not with the usual three finalists, but with a single finalist: Rosie Castro.

Council members sensed the magnitude of the moment and didn’t want to mar it by bringing in two other candidates for Rosie’s moment of triumph on Thursday. And besides, it would have been unfair to the other applicants to bring them back for a second round of interviews when we all knew who deserved the appointment.

In fact, there was a vague sense of sheepishness to the process, because some council members felt unworthy of grilling a legendary activist and civil rights crusader who not only played a huge role in transforming our city — but also raised twin sons (Julián and Joaquin) who have been dominant figures in San Antonio politics over the past two decades.

East Side Councilman Jalen McKee-Rodriguez, the first openly gay man ever to serve on the council, prefaced his question for Castro on Wednesday with this thought: “It is an honor to interview you and I feel a little bit silly interviewing you for a place on the dais.”

That same afternoon, Adriana Rocha Garcia looked to fellow Councilwoman Teri Castillo and mused, “Do we really have to ask questions?”

It was a rhetorical question for which the obvious answer was “no.”

After all, Rosie’s résumé speaks for itself.

As a young student at Our Lady of the Lake University, she followed migrant families to the Midwest and helped create a mobile school that taught migrant children. Later, in the Edgewood Independent School District, she worked as a preschool teacher.

Those experiences informed her son Julián’s later commitment to creating a state-of-the-art pre-K program (Pre-K 4 SA) during his mayoral tenure.

In 1971, Rosie took on the entrenched power of San Antonio’s Good Government League and ran for City Council as part of a four-person Committee for Barrio Betterment slate. The Mexican American Legal Defense and Educational Fund cited that campaign in its successful legal fight to bring single-member council districts to this city.

While working for the city of San Antonio, Rosie helped recruit women to the fire department.

She successfully advocated for a downtown campus for University of Texas at San Antonio and for a Mexican American collection in the San Antonio Public Library.

She has volunteered her time to more community organizations than most of us could even name.

She tirelessly worked in 1981 to help her friend María Berriozábal become the first Latina elected to the San Antonio City Council.

“She opened the door for people who would not win, election after election, because the cards were stacked against us,” Berriozábal told the council Thursday. “This woman is an incredible leader.”

The essence of Rosie Castro’s greatness is her belief in the principle that opportunity is a precious commodity that must be cultivated, passed on and expanded with each generation.

In a recent interview with me on the KLRN show “Texas Talk,” Rosie recalled how her mother, a Mexican immigrant who was pulled out of school in the third grade, dreamed of being a journalist but knew she had no chance without an education.

She wanted better for her daughter.

“I think she was committed to the idea that if she didn’t have the chance, maybe I would have the chance,” Rosie said.

Rosie applied that same philosophy to her sons — and the community she called home.

“For me, the greatest privilege has been to be able also to offer some opportunities to my sons,” she told council members Thursday.

“And to know that, like you, they are committed to making sure that everyone in this beloved city has the opportunity to grow, to live, to prosper. Not to hate, but to love. And to be the very best that they can be.”

As Rosie was quick to point out this past week, her stint on the council will only be about three months. It won’t offer much time for policymaking. It will primarily be about constituent engagement and stewardship of existing infrastructure projects.

But her appointment means so much more than a three-month City Council tenure.

It means that someone who devoted her life to helping others shine will get her own much deserved moment in the sun.
