Oh??
13 Then cometh Jesus from Galilee to the Jordan, unto John, to be baptized by him.
14 But John stayed him, saying: I ought to be baptized by thee, and comest thou to me?
Why; in ALL of His ministry; do we find no instance of Jesus ever baptizing anyone?
Your question: “Why; in ALL of His ministry; do we find no instance of Jesus ever baptizing anyone?”
From Catholic answers:
All things considered, we can safely state, therefore, that Christ most probably instituted baptism before His Passion. For in the first place, as is evident from John, iii and iv, Christ certainly conferred baptism, at least by the hands of His Disciples, before His Passion. That this was an essentially different rite from John the Precursor’s baptism seems plain, because the baptism of Christ is always preferred to that of John, and the latter himself states the reason: “I baptize with water ... [Christ] baptizeth with the Holy Ghost” (John, i). In the baptism given by the Disciples as narrated in these chapters we seem to have all the requisites of a sacrament of the New Law: (I) the external rite, (2) the institution of Christ, for they baptized by His command and mission, and (3) the conferring of grace, for they bestowed the Holy Ghost (John, i). In the second place, the Apostles received other sacraments from Christ, before His Passion, as the Holy Eucharist at the Last Supper, and Holy ‘orders (Conc. Trid., Sess. XXVI, c. i). Now as baptism has always been held as the door of the Church and the necessary condition for the reception of any other sacrament, it follows that the Apostles must have received Christian baptism before the Last Supper. This argument is used by St. Augustine (Ep. clxiii, al. xliv) and certainly seems valid.
