that IS funny. good story.
it was posted: ‘When you accompany your husband to his church, you are going for his sake and not for your own benefit.’ i would disagree here. there is much that we can learn from our separated brothers, the protestants. while i am a convert, and so see the RCC as having ‘the fullness of truth’, i know from experience that there is much that can be gained in Bible knowledge, spiritual discernment, zeal (especially zeal!), prayer, and evangelism from protestants.
i tell my catholic friends whenever i go to a protestant church that i’m going for a ‘pep talk’, cuz they always cheer you up and make you excited. sometimes it’s groundless, but it’s always exciting.
i would counsel not making the sign of the cross where you think it would unnecessarily divide. i think the kind and charitable thing, in most circumstances involving more than one religious tradition, is to find ‘common ground’ from which to start.
praying a rosary in a protestant church would be an example of being unnecessarily divisive. reading the Bible in a protestant church would be finding common ground. but what translation???
during meals, i usually pray to myself, in my head. it’s too easy for me to WANT to draw attention to myself for my ‘piety’, so i intentionally mortify that by praying internally.
others may have a fear of publicly demonstrating their faith. for them, it might be GOOD to pray in a way that others can see, to overcome that fear.
i don’t think there’s a catch all for this sort of thing. just try to be sensitive to others feelings and beliefs, and try to do what you think will love them in a way they can understand.
God bless.
