((Kaika)) i think you are handling this in a kind and caring way, you recognize your parents need for something greater than themselves to enter thier life and give it some new energy or life that had gone missing and in a lot of ways a positive grounded and strong loving faith can repair many so called voids for us... its great that you are giving them the space they need to develop and find what they need...

i hope they have explained to you that your own faith is something which is so private, so deep, so valuable that no other can ever take or change it from what you decide it should be...
