...if anyone looks with faith at the mystical table and the Bread of Life placed on it, he sees the Person of the Word of God, Who was made flesh for our sake and dwelt among us (John 1:14). If he shows himself a worthy receptacle, he will not only see but become a partaker of Him, receive Him to dwell within him, and be filled with His divine grace.

'Now we are the sons of God'. This is the starting point of adoption. However, 'it does not yet appear what we shall be: but we know that, when He shall appear, we shall be like Him; for we shall see Him as He is' (I Jn. 3:2). This is the perfection of adoption of sons and renewal which God bestowed on us in Christ, and of which John says in his Gospel that, 'Christ gave power to become the sons of God, even to them that believe on His name: which were born, not of blood, nor of the will of the flesh nor of the will of man, but of God' (Jn. 1:12-13).

The Light of Christ illumines all.

If from one burning lamp someone lights another, then another from that one, and so on in succession, he has light continuously. In the same way, through the Apostles ordaining their successors, and these successors ordaining others, and so on, the grace of the Holy Spirit is handed down through all generations and enlightens all who obey their spiritual shepherds and teachers.

... we grapple with this 'law of sin' (Rom. 8:2) and expel it from our body, establishing in its place the surveillance of the intellect. Through this surveillance we prescribe what is fitting for every faculty of the soul and every member of the body. For the senses we prescribe what they should take into account and to what extent they should do so, and this exercise of the spiritual law is called self-control.

Let none of you have a soul which is barren and without fruit. Let nobody be unloving or unreceptive to the spiritual seed. May each of you eagerly accept the celestial seed, the word of salvation (cf. Lk. 8:11), and by your own efforts bring it to perfection as a heavenly work and fruit pleasing to God. Let no one make a beginning of a good work which brings no fruit to perfection (cf. Lk. 8:14), nor declare his faith in Christ only with His tongue.

... the passion for popularity brings such injury upon those it masters that it shipwrecks faith itself. Our Lord confirms this when He says, 'How can you have faith in Me when you receive honour from one another and do not seek for the honour that comes from the only God?' (cf. Jn. 5:44).
