St Agnes practice to be single

St Agnes, a 13 year old female Christian in Roman days didn't want to merry and was strip naked and who ever looked at her body was blinded , when they try to burn her the flames didn't touch her. Wanna know why she didn't want to merry, because she was practicing the Original teachings of Christianity https://youtu.be/M4o1dc41r28 https://youtu.be/EVVQ5_RUQHM
