June 19: Solemnity of Corpus Christi
"Although the Eucharist is solemnly celebrated every day, we deem it fitting that, at least once a year, a more honored and solemn remembrance be observed. The other things we commemorate, we grasp with the spirit and the mind, but do not for that reason obtain their real presence. However, in this sacramental commemoration of Christ, even though under a different form, Jesus Christ is truly present among us in His own substance. Indeed, as He was about to ascend into heaven, He said: 'And behold, I am with you always, until the end of the age (Mt 28:20)."
