Actually, while upholding the the trinitarian formula,
There has been a theological controversy over the question as to whether baptism in the name of Christ only was ever held valid. Certain texts in the New Testament have given rise to this difficulty. Thus St. Paul (Acts 19) commands some disciples at Ephesus to be baptized in Christ’s name: “They were baptized in the name of the Lord Jesus.” In Acts 10, we read that St. Peter ordered others to be baptized “in the name of the Lord Jesus Christ”. Those who were converted by Philip. (Acts 8) “were baptized in the name of Jesus Christ”, and above all we have the explicit command of the Prince of the Apostles: “Be baptized every one of you in the name of Jesus Christ, for the remission of your sins (Acts 2).
Owing to these texts some theologians have held that the Apostles baptized in the name of Christ only. St. Thomas, St. Bonaventure, and Albertus Magnus are invoked as authorities for this opinion, they declaring that the Apostles so acted by special dispensation. Other writers, as Peter Lombard and Hugh of St. Victor, hold also that such baptism would be valid, but say nothing of a dispensation for the Apostles. The most probable opinion, however, seems to be that the terms “in the name of Jesus”, “in the name of Christ”, either refer to baptism in the faith taught by Christ, or are employed to distinguish Christian baptism from that of John the Precursor.

ONLY??? NEVER say ONLY when referring to the NAME OF JESUS!
