(God is within her, she will not fall; God will help her at break of day.) Confused but excited by her newfound abilities, Ava soon realizes she's in over her head, but her need for a helping hand may be a blessing in disguise.

(She is clothed with strength and dignity, and she laughs without fear of the future.) After tasting the good life with JC, Ava crashes a swanky tech party with his friends. Mary goes gunning for the people behind the attack on her sisters.

(Put on the full armour of God, so that you can take your stand against the devil’s schemes.) Ava takes her first steps towards understanding the halo's power, but a baptism by fire at the hands of the Order leaves her feeling burned.

(The whoredom of a woman may be known in her haughty looks and eyelids. If thy daughter be shameless, keep her in straitly, lest she abuse herself through overmuch liberty.) As Ava contemplates starting over, she recalls being left to the tender mercies of the orphanage. The Sister Warriors suit up for a dangerous mission.

(Enter through the narrow gate. For wide is the gate and broad is the road that leads to destruction, and many enter through it.) While Mary squares off with Sister Lilith, Ava begins to open up to JC, and Jillian Salvius fires a warning shot at the Church.

(Although the Lord gives you the bread of adversity and the water of affliction, your teachers will be hidden no more; with your own eyes you will see them. Whether you turn to the right or to the left, your ears will hear a voice behind you, saying, "This is the way; walk in it.") Ava experiences a come-to-Jesus moment courtesy of Mary, who pulls no punches as she shows her just how many souls have their own cross to bear.

(You were taught, with regard to your former way of life, to put off your old self, which is being corrupted by its deceitful desires; to be made new in the attitude of your minds; and to put on the new self, created to be like God in true righteousness and holiness.) Hoping to find some answers, Ava puts her faith in science. Meanwhile, Cardinal Duretti's machinations sow seeds of dissension inside the Order.

(The wise woman builds her house, but with her own hands the foolish one tears hers down.) Secrets are revealed and a Sister Warrior mysteriously returns to the fold as Ava and her allies attempt to keep a sacred object out of the wrong hands.

(The weapons we fight with are not the weapons of the world. On the contrary, they have divine power to demolish strongholds.) Infiltrating the Vatican to find a tomb hidden deep underground for a millennium? Hell, Ava may need a miracle to pull off this mission.

(Do not be afraid of what you are about to suffer. I tell you, the devil will put some of you in prison to test you, and you will suffer persecution for ten days. Be faithful, even to the point of death, and I will give you life as your victor’s crown.) In shock over the contests of the tomb, Ava no longer knows what – or who – to believe as she tries to divine the true history of the halo.

(Each one should test their own actions. Then they can take pride in themselves alone, without comparing themselves to someone else, 5 for each one should carry their own load.) Ava and Beatrice jump into action when they meet an ally eager to take down a self-proclaimed prophet and his followers. Tragedy strikes at the convent.

(Do not lie to each other, since you have taken off your old self with its practices and have put on the new self, which is being renewed in knowledge in the image of its Creator.) A mysterious nun makes contact with the OCS, while Adriel proposes a partnership to the pope. Lilith turns to an unexpected source for help.

(For there is nothing hidden that will not be disclosed, and nothing concealed that will not be known or brought out into the open.) After the Order sends out an urgent call, Beatrice and Ava connect with old friends in Madrid and stop by a museum. Jillian investigates an anomaly.

(The sacrifices of pagans are offered to demons, not to God, and I do not want you to be participants with demons. You cannot drink the cup of the Lord and the cup of demons too; you cannot have a part in both the Lord’s table and the table of demons.) As a bizarre plague sweeps the city, Ava uncovers new revelations about Miguel – and Adriel’s methods. Lilith explores new possibilities.

(For even the Son of Man did not come to be served, but to serve, and to give his life as a ransom for many.”) Seeking Lilith's whereabouts, the sisters and Miguel visit Jillian. An unnerving discovery upsets Camila. Conflict erupts over Adriel at the conclave.

(Those who hope in the Lord will renew their strength. They will soar on wings like eagles, they will run and not grow weary, they will walk and not be faint.) The Order and their allies prepare for a showdown against Adriel at his new cathedral, but learn their adversaries have been making plans of their own.

(Precious in the sight of the Lord is the death of his faithful servants.) After an intense battle, Ava's halo saves a life, while one of Adriel's followers has a crisis of faith. Camila finds herself behind enemy lines.

(You will seek me and find me when you seek me with all your heart.) Ava visits the other realm and returns with a new plan to end Adriel’s unholy charade – but it will require superhuman strength and painful sacrifices.
