Today is the feast of St. Albert the Great, Doctor of the Church. From his eucharistic work, On the Body of the Lord, Distinction 1:
This is the sacrament of sacraments, the Eucharist, containing every grace, food giving growth for eternal life, viaticum strengthening us to complete the journey of our exile, and the pledge of eternal salvation, and the communication of all holiness.
I say, therefore, that this sacrament is placed in six genera because of the innumerable graces that it contains. Nor is there one genus that is able to contain so many graces. For it is in the genus of grace, gift, food, communion, sacrifice, and sacrament.
[Albert the Great, On the Body of the Lord, Surmanski, tr., The Catholic University of America Press (Washington, DC: 2017) p. 31.]
