In the state of texas can I record a conversation in person to which I am a consenting party?

I am employed by a mega church and they had a magician come to perform for the children. As a teacher of the children as well as a bible believer I questioned having magic in a Christian church. I was immediately removed from groups and not allowed back to work but given paid time off until having a meeting with HR. Now this is the largest church in the whole of America and is under constant video and audio recording and as far as I am aware nowhere inside the building with the exception of restrooms is any form of privacy actually expected. I recorded the conversation between myself and HR and the HR representatives told me I should not be the prophet who gets my head cut off. I take this as an illegal threat of human life and would like to expose, file a lawsuit, or even criminal charges but need to know if the recording is admissible in court and legally obtained.
