Matthew 28:19 "... has been disputed on textual grounds, but in the opinion of many scholars the words may still be regarded as part of the true text of Matthew. There is, however, grave doubt whether they may be the ipsissima verba [real words] of Jesus. The evidence of Acts 2:38; 10:48 (cf. 8:16; 19:5), supported by Gal. 3:27; Rom 6:3, suggest that baptism in early Christianity was administered, not in the threefold name, but "in the name of Jesus Christ" or "in the name of the Lord Jesus." This is difficult to reconcile with the specific instructions of the verse at the end of Matthew."

"...So long, then, as we have Jesus with us fulfilling the promise which runs, "Lo, I am with you always unto the consummation of the age," we cannot fast nor be in want of food, so that, because of want of it we should desire to take and eat the forbidden leaven..."

“According to Eusebius (H. E. vi. 36) the Commentaries on the Gospel of Matthew were written about the same time as the Contra Celsum, when Origen was over sixty years of age, and may therefore be probably assigned to the period 246-248. Of the twenty-five books into which the work was divided, the first nine, with the exception of two fragments, are lost; books x.-xvii, covering the portion from Mt. 13:36 to 22:33, are extant in the Greek, and the greater part of the remaining books survives in a Latin version, which is co-extensive with the Greek from book xii. 9 to book xvii. 36, and
