After discussion with the head of the liturgical council in the UK (at least, he was head when he came to speak to us), our team were given permission to receive the Eucharist at all Masses taking place on our final day of Mission... in most schools, that is only twice, but very rarely it can be three or four. We all play a very active role in the Mass, and his opinion was it was of great benefit to those we minister to to see other young people receiving the Eucharist reverently... and that it would be inappropriate for us not to participate fully... anyway, that is a particular case, and it has come from our necessity to be present at all the Masses, rather than us thinking we need to receive Jesus lots and lots of times in one day... Just another perspective as well...
