He has suddenly realized that Juliet is about to wake up and he is the only one who knows it. She will be having a rough time sealed up in a tomb with a bunch of rotting corpses, so someone better rescue her.
Because he knows and we know that she is not ready to go to church because of being apparently dead.
In Act V, Scene One of Shakespeare's "Romeo and Juliet," the four characters who confront one another are Romeo, Juliet, Paris, and Friar Laurence. Romeo arrives at Juliet's tomb, where he encounters Paris, who believes he is there to mourn Juliet. A confrontation ensues between Romeo and Paris, leading to a tragic turn of events. Meanwhile, Friar Laurence arrives in time to witness the aftermath of their conflict.

If you are talking about Act V, she goes back to the cemetery. Permanently.

Friar Lawrence (V, iii, 158)
Friar Laurence
If anything, he is more of an incidental character in WIlliam Shakespeare's "Romeo & Juliet." He serves as a plot device, which unintentionally foils Friar Laurence's plan for the two star-crossed lovers, and does little else in the play, only appearing in one scene toward the end of the play (Act V Scene 2)

They go inwhen you do a low V and they go out when you do a high V.
A suitable excerpt from Act V Scene iii of Romeo and Juliet that reflects this idea is when Friar Laurence says, "A greater power than we can contradict hath thwarted our intents." This line suggests that the interference and involvement of various characters ultimately led to Romeo and Juliet's tragic fate.
I hope this helps; I just did a quick overview in each scene of the Act (IV). In Scene I of Act IV: Friar Laurence meets with Paris and they talk, before Juliet interrupts. Paris leaves and Juliet weeps to the Friar about her marriage that is being planned with Paris, and she ask for help from the Friar. The Friar gives her a potion that will make her appear to be dead. Their plan after this was supposed to go as follows: she will not have to be married, her family will bury her, and Romeo will come and rescue her. At this point in their plan they would reveal what they had done, to their families. In Scene II of Act IV: Juliet goes to her father to apologize about how she did not want to marry Paris, and how she had made a big scene. Her father accepts her apology, and moves up the wedding by one day. (This plays a big part, as it messes up the Friar's plan to tell Romeo to rescue Juliet from the burial chamber in time.) In Scene III of Act IV: Juliet ponders what will happen when she drinks the potion, and what it will be like when she is put in the burial chamber (Will Romeo not come in time, or will the ghost and demons of Tybalt and her other family members haunt her.) She does not want to marry Paris, so if the potion does not work she plans to kill herself with a dagger. At the end of the scene she drinks the potion. In Scene IV of Act IV: The family is getting ready for the wedding. Lady Capulet tells the Nurse to wake up Juliet. In Scene V of Act IV: The Nurse and the Family discover Juliet, and believe that she is dead. The Friar (who knows the truth) and Paris find out soon after. All of the flowers, food, and preparations from Juliet and Paris's wedding have been moved to be used for her funeral.
