Some people do it here, most don’t. Its not required. It is personal preference. It feels like someone is saying something you agree with and cross yourself to seal it. I want almighty God to have mercy on me, forgive my sins and bring me to everlasting life. Amen. Here I’ll cross myself in the name of the trinity to prove it. I don’t do it every time. Sometimes it feels rote but other times it means more.
Hello your ‘Qwikness’
I like your term "to seal yourself’ It’s verbal, its physical, it’s spiritual,
Actually saying, ‘Amen,’ seals it; Amen = ‘
let it be so,’ or ‘
so be it.’
It is simply
a form of affirmation or confirmation of the speaker’s own thought, sometimes introducing it, sometimes following it.
Jer 28:6 and the prophet Jeremiah said,
"Amen! May the LORD do so; may the LORD make the words which you have prophesied come true,
1 Chronicles 16:36, “Blessed be the Lord God of Israel from eternity; and let the people say Amen and a hymn to God”,
Psalm 105:48, "Blessed be the Lord, the God of Israel from everlasting: and let all the people say:
so be it"

1 Why do we make the sign of the cross?
a. To remind us of the Blessed Trinity—Father, Son and Holy Ghost. We repeat their names.
b.
To remind us that the Son of God died on a cross for all men. Before Calvary it was a sign of disgrace. Christ made it a thing of glory and power.
c.
To stir up our faith. It recalls that God is one and God is three; it recalls that the Second Person of the Trinity died for all men; it professes our faith; it identifies the Catholic. That is why the family of our story felt so secure, so much safer, as soon as they saw those American soldiers make the sacred sign.
d.
To strengthen our hope. By making this sacred sign we express the hope that through the cross all blessings will come to us.
e. To kindle and feed our charity.** Making this sign recalls the limitless love of Him who died upon the cross.** We determine to return love for love.
- The uses of this sacred sign in the Catholic Church are practically without limit:
a.
According to many our Lord and the Apostles used it. Many affirm that our Lord blessed the Apostles with the sign of the cross on the day of His Ascension. Certainly the early Christians used it constantly.
b. It is used in all the public worship of our Church:
i. The sign of the cross in some form or other is made about 54 times during Holy Mass.
ii. It is used frequently in the Divine Office or daily prayer of the priest.
iii. It is used in all blessings bestowed by bishop and priest.
iv. It is used in all the sacraments: 14 times in Baptism; 17 times in Extreme Unction. Yes, even in the semi-darkness of the confessional the priest makes the sign of the cross over you.
v. It is used in everything blessed for the service of God—altars, linens, holy water, etc.
c. It is used frequently in personal devotions:
i. In the morning and evening to seek God’s help.
ii. Before and after prayer, against distractions.
iii. Before and after meals, asking God’s blessing.
iv. In dangers of soul, like temptation and occasions of sin.
v. In dangers of body like storms, sickness, travel.
vi. Before our chief actions and undertakings, to make them pleasing to God and to obtain God’s help in performing them properly.
Let me quote the instructive words of St. Gaudentius:
"Let the sign of the cross be continually made on the heart, on the mouth, on the forehead, at table, at the bath, in bed, coming in and going out, in joy and sadness, sitting, standing, speaking, walking—in short,** in all our actions**. Let us make it on our breasts and all our members, that we may be entirely covered with this invincible armor of Christians."
God bless,

John
