There are numerous factual errors in this piece:
First, concealed carry wasn’t signed into law in 1991; that was the “Ma Richards” regime, and she stoutly refused to sign, one of the reasons that George W. Bush was elected to replace her after only one term.
He signed it into law.
Second, concealed carry is NOT prohibited in churches in Texas, though, individual churches can ban it if they choose to; mine, formerly Episcopal, does not ban it.
At my best friend’s Pentecostal church in Mesquite , the USHERS are armed to protect the congregation, ministers and offering money. He tells me this is more common than one might think.
