This thought just occurred to me, is this a play in and of itself, or is it a prelude to an altar call?
If you are strong in your faith in Christ and the teachings of the Catholic Church, go no matter what. If you are shaky on things, or have been having any crisis of faith, you may wish to find out the specifics of whether or not it is just a play and opt out if it is more.
I would go and use it as an opportunity for witnessing for Christ and the fullness of truth of the Catholic Church.
God Bless,
