Why did not Jesus personally baptize anyone?

We see Jesus telling Nicodemus in Jn 3: 5: > Jesus answered, “Very truly I tell you, no one can enter the kingdom of God unless they are born of water and the Spirit. - John 3:5 We also read at Jn 4: 1-2: > Now Jesus learned that the Pharisees had heard that he was gaining and baptizing more disciples than John (although in fact it was not Jesus who baptized, but his disciples). One wonders why Jesus did not personally baptize anyone in spite of his having emphasized the importance of Baptism. My question therefore is: **Why, according to Catholic Church, did not Jesus personally baptize anyone?**
