Mark 14:17-18
“And when evening was come, HE COMETH WITH THE TWELVE.  AND WHEN THEY WERE AT TABLE EATING,  Jesus saith: Amen I say to you, one of you that eateth with me shall betray me.”

Luke 22:13-14
“And they going, found as he had said to them, and made ready the pasch.  
AND WHEN THE HOUR WAS COME, HE SAT DOWN, AND THE TWELVE APOSTLES WITH HIM.”

The Gospel of St. John does not tell us precisely who was at the Last Supper, but does mention that Christ washed the feet of the Disciples, by which is meant the 12 Apostles as the names of two of the Apostles are given, Peter, and Judas. 

Those who foment for women priests often engage in a pernicious error, namely by distorting the meanings of two words: Disciple and Apostle.  The word "Disciple" means "learner", from the Latin, discipulus.  The word "Apostle" means "messenger" from the Greek, apostolos.  The 12 Apostles were messengers, given the commandment by Christ to preach and to baptize.
