According to Catholicism and Eastern Orthodoxy, which Apostle is believed to have celebrated the Eucharist first? The question is quite simple. Is there any tradition of any apostle in particular who is believed to be the first to say mass, following the Resurrection of Christ? I am not overly confident that such a traditional belief exist within either Eastern Orthodoxy or Catholicism! One may use references from Sacred Scriptures, the Early Church Fathers or other sources if applicable like the writings of recognized Christian mystics, like Catherine of Siënna to help find an answer.
