Your testimonies are fully confirmed; Holiness befits Your house, O LORD, forevermore.
For they disciplined us for a short time as seemed best to them, but He disciplines us for our good, so that we may share His holiness.
"If but ten of us lead a holy life, we shall kindle a fire which shall light up the entire city."
--St. John the Chrysostom
...holiness is the opposite of the reality of this world...
The liturgy teaches this holiness most explicitly. Before offering the eucharistic gifts, the celebrant says: "Holy things for the holy" and the assembly responds, moved by this awesome invitation, confessing their unworthiness, "One is holy, one is Lord, Jesus Christ, in the glory of God the Father. Amen." The One who is uniquely holy in his nature is Christ. Those who are his members are holy only through sharing in his unique holiness.
