When we make the sign of the cross, we say, "In the name of the Father, and of the Son, and of the Holy Spirit." When we make the sign of the cross, are we, as Fr. Richard Rohr asks, just going through the motions, or are we thinking of the Trinity?
Christianity joins the 2 other Abramic religions in worshiping one God. But, our God is one in three. Our God is a family. Our God is LOVE.
Our spirituality is not based on an individualism, although our country is. Our spirituality is based on a Person--a Trinity of Persons who are LOVE.
When we "bless ourselves" with the sign of the cross, are we really, consciously blessing ourselves? The sign of the cross is a way to bring to mind the Love that is our Creator God and to ask God to bless us with the Love that is the Trinity.
It is a Trinitarian blessing brought from God to our own consciousness.
Don't let it become just another thing to do.
