"Today is the Solemnity of All Saints, a holy day of obligation. The Church honors all those who are with God, the innumerable men and women who chose fidelity to Christ." (--from Divine Office, About Today, Feast of All Saints)
"Obligation" is our being tied together. It is our responsibility to our brother and sister beings.
"Christ" is the creative, loving, assisting manifestation of God.
This is what a saint is, one who is with God.
And all of us, each of us, is with God.
We might not yet realize it.
But it is true.
Look at this truth.
This will be seen.
