I could not complete my article "Barnabas, His Gospel and Its Credibility"[1], due to some other assignments. Although the article is incomplete, it would be advisable if you manage to go through both of its installments once again. You wrote about the 'Epistle to Hebrews'. According to modern research it was not written by Barnabas. Of course Barnabas was a scholarly person and he composed a "Gospel", but the attribution of the 'Epistle to Hebrews' to him is not credible. Actually there exists another 'Epistle of Barnabas'. It has been included in "THE ANTE-NICENE FATHERS, TRANSLATIONS OF The Writings of the Fathers down to A.D. 325", Ed. THE REV. ALEXANDER ROBERTS & JAMES DONALDSON, WM. B. EERDMANS PBLG. CO., GRAND RAPIDS, MICHIGAN, Vol. I, pp.133-149. Initially there is a three page 'Introductory Note' to it. Necessary footnotes have also been afforded to it. Its attribution to Barnabas is also doubtful. However, it is a worth-reading treatise. As regards his Gospel, The Oxford Dictionary of the Christian Church asserts:
Gospel of Barnabas was declared a rejected book in the Decretum Gelasianum by Pope Gelasius [Pope of Rome 492-96]. According to E. Von Dobschutz, it is a private compilation which was composed in Italy (but not at Rome) in the early sixth century.[2]
