From Pius Parsch’s The Church’s Year of Grace:
The Church foresees the entire work of redemption accomplished in the birth of Christ. In Christ we have received every good, in Him we have received God’s greatest gift.
Everything our faith holds as worthy of desire we obtain in Christ — divine adoption, the Church, the Eucharist, heaven…It is as though Mother Church wishes to pour out anew at Christmas the fullness of her grace-treasures.
Shouldn’t these reflections help in understanding the symbolism of the Christmas tree? Yes, shower your gifts, your joy, your kindness, and your love upon all, for these are symbols of Christ, the greatest Gift heaven itself could send us.

May you have a blessed Christmas season!
