Does the Catholic Church approve of Opus Dei?

I understand that there has been some confusion surrounding the Catholic Church's stance on Opus Dei. Can you clarify whether or not the Church approves of Opus Dei and explain the nature of their relationship? Are there any specific teachings or beliefs of Opus Dei that align with or contradict the teachings of the Catholic Church? Additionally, are there any historical or cultural factors that have influenced the Church's perspective on Opus Dei?
