To be more specific about Fr. Zendejas --
He is a dedicated priest. He recently drove hundreds of miles to say a funeral Mass for a relative of an SSPX parishioner. The deceased was in Laredo, which had no Traditional Mass options (Fr. Voigt just started a Mass center there a couple weeks ago)
He is zealous, apostolic, and full of love for the Faith. He is active enough, but he obviously has a solid prayer life to back it up when you look at his results. He is for publicly professing our Faith.
He is a faithful spiritual son of the Cristeros -- those manly, brave souls that energetically worked for the reign of Christ the King. He has many of the same virtues we read about in the lives of Mexican saints.
