I am pleased you are warming up to Saintly Intercession with God on our behalf.
First off 7-b, it's 'hand', singular. Secondly, the Sign of the Cross is not simply an action but a prayer in itself. Not only that, just like Holy Water, Rosaries, and Medals, ect. it is a Sacramental.
Okay
Undefined? Really? I thought Catholics on this thread have defined it clearly. In case you've missed it, in the Sign of the Cross, we profess the deepest mysteries of the Christian Faith: the Trinity....Father, Son, and Holy Spirit--and the saving work of Christ on the Cross on Good Friday. The combination of the words and the action are a creed—a statement of belief. We mark ourselves as Christians through the Sign of the Cross.
Surley you are not suggesting that one's devotion to worship God is a bad thing?
Nope.... it has nothing to do with "impressing" other people. Do you not pray (witness your faith) in public, say before a meal at restaurants? For Catholics, the Sign of the Cross is a simple way to witness our faith to others. As St. Cryil so wisely say's:
Yes, there are. Remember.... you asked!
1. It's a prayer.
2. We open ourselves to grace.
3. We sanctify the day.
4. We commit our whole self to Christ.
5. We recall the Incarnation.
6. We remember the Passion of Our Lord.
7. We affirm the Trinity.
8. We focus our prayer on God.
9. We affirm the procession of Son and Spirit.
10. We confess our faith.
11. We invoke the power of God’s name.
12. We crucify ourselves with Christ.
13. We ask for support in our suffering.
14. We reaffirm our baptism.
15. We reverse the curse.
16. We remake ourselves in Christ’s image.
17. We mark ourselves for Christ.
18. We soldier on for Christ.
19. We ward off the devil.
20. We seal ourselves in the Spirit.
You're welcome.
