text: You wouldn't be always puzzled if you read more about the Church and what it believes.  In this
  case, see Canon 900 §1:  "The only minister who, in the person of Christ, can bring into being the sacrament of the Eucharist, is a validly ordained priest."
  So in answer to your question:  Yes, Jesus's presence in the Eucharist requires the person of Christ, who alone is the priest.   It may seem dismissive of what the Son of God is capable of, but we had that debate during the Reformation, and the RCC decided that your view was so incorrect as to be a heresy.
