From Observatório Católico [roughly translation]:

For those who feared that the Church might approve of an abused indigenous rite, there could be no better answer than this! Who will study and give an opinion on the Amazonian rite is Cardinal Robert Sarah  Prefect of the Congregation for Divine Worship.

Born in the Republic of Guinea (Africa), Sarah is well known for his great zeal for the Church’s doctrinal and liturgical tradition. So… calm your little heart!
