Not wanting to discuss a textual issue, but just a little background prior to my query about Logos translations:
I have been having a discussion w. someone very learned who suspects that Matthew 28.19 is not original.  I realize that this is an old canard and I have already sent him many early writers who refer to this text (Martyr, Ignatius, etc.).  He says that if I could locate a reading, say, in the 200’s, contains the reading that he would concede.  I have already quoted to him the Sahidic translation, which is among the earliest translations of the Greek text.
Enter Logos:  I am just wanting to know what is the earliest translation available in Logos?  Coptic, Sahidic, Ethiopic?  If at all possible I would greatly appreciate a link in Logos (or otherwise, e.g., Amazon).
He really is a fine, humble and sincere Christian man—who is also very scholarly (he was a Bible college president for 20 years).  I have zero doubt that this reading is original—just thinking that the early translations might actually be a good route to take w. this gentleman.  
Thank you in advance.
