The Roman Missal: Proper of Saints, October (English) 3
1[October 2. Feast of our Holy Guardian Angels.—Double.]
3Prayer. Deus qui. O God, who, by an unspeakable providence dost vouchsafe to send thy angels to guard us; grant to thy suppliants to be ever defended by their protection, and to rejoice in their eternal society. Through our Lord, &c.
4Lesson. Exodus xxiii. 20—23. Thus saith the Lord God, Behold, I will send my angel, who shall go before thee, and keep thee in thy journey, and bring thee into the place that I have prepared. Take no notice of him, and hear his voice, and do not think him one to be contemned, for he will not forgive when thou hast sinned, and my name is in him. But if thou wilt hear his voice, and do all that I speak, I will be an enemy to thy enemies, and will afflict them that afflict thee: and my angel shall go before thee.
6[Gospel, as on May 8th, page 582. Credo.]
7Offertory. Bless the Lord, all ye his angels: you ministers of his who execute his word, hearkening to the voice of his orders.
8Secret. Receive, O Lord, the offerings we bring, in veneration of thy holy angels; and mercifully grant, that by their perpetual patronage we may be delivered from present dangers, and arrive at life eternal. Through our Lord, &c.
10Postcom. Sumpsimus. We have received divine mysteries, O Lord, rejoicing on the festival of thy holy angels: we beseech thee, that by their protection we may be ever freed from the snares of enemies, and defended against all adversity. Through our Lord, &c.
