From the remembrances of St. Agnes:
As if that was not enough, at the moment of my death, God still testified about His love for me, strengthening me through signs; and, thanks to that, arousing faith in all those who witnessed these events . How great a testimony I bore with my existence, so that God may be recognized and His holy Name may be known in the whole world. From up here, after one can see exactly how many souls were later nourished by this hope, which God deigned to show through my martyrdom (Compendium III, p.119-120).
 It is said that the miraculous signs that took place during the tortures, caused the conversion of 160 pagans.
From the teachings of St. Agnes:
Achieving holiness after the death requires enormous and long-lasting sufferings, while during lifetime the worst sufferings would be considered the lightest punishment in Purgatory. Also, not everyone gets this chance. Many souls will never again sanctify themselves and will never reach the state of eternal joy. Eternal suffering awaits them.
I could never understand how one can take such risks, to risk such a cruel eternal fate for a moment of sin. Therefore, the whole wisdom of man lies in this: to deepen and to strengthen his faith, thanks to which it is increasingly easier to deny himself for the cause of his future life (Compendium IV, p.158).
Saint Agnes, who never risked the loss of eternal life for a moment of sin and with joy suffered death by martyrdom for the One, who died for all of us, I ask you humbly, deign to intercede for me in every minute of this day and obtain for me the grace (mention your request).
Let your prayer give me comfort in times of trials and torments. Be my friend in times of loneliness and abandonment, and obtain for me from your Spouse, Jesus Christ, the eternal happiness in Heaven. Holy innocent virgin, who paid the greatest price for preserving fidelity to Christ, obtain for me the grace of complete purity of the soul and the body. Amen.
Our Father …
Hail Mary …
Glory be to the Father …
Litany to Saint Agnes.
