Pentecost - St. Ephraim The Syrian
“Now the Prophets performed all other signs; but on no occasion supplied the deficiency of members. But the deficiency of the body was reserved, that it should be supplied through our Lord; that souls might perceive that it is through Him that every deficiency must be supplied. It is meet, then, that the prudent should perceive that He Who supplies the deficiencies of the creatures, is Master of the formative power of the Creator.
But when He was upon earth, our Lord gave to the deaf and dumb, the power of hearing and of speaking tongues which they had not learned; that after He had ascended, men might understand that He gave to His disciples the power of speaking in every tongue.”
