People seek outside the fullness of the faith because they are poorly catechized to know the faith and thus are not in right relationship with God - which we all naturally seek - so they go elsewhere looking for the green grass of Jesus.
Hope they find the green grass of Jesus, but it will always be greenest in experience at the one true church, once they are properly understanding of it, but for now, they are unable to see that and will go off searching.
Find Christ! He’s in the Eucharist, in body, in blood, in soul, and in divinity. If you don’t know that, then find Him where you can for Goodness sake. It’s like sometimes you break with your girlfriend to find love...only to find she was the love of your life right there.
“People seek outside the fullness of the faith “
Pentecostals are the ones with the ‘fullness of faith” in the HOLY SPIRIT . That has nothing to do with the “Prosperity Doctrine”, which distorts the Baptism of the Holy Spirit, if not shown in the content of Scripture.
God meets our needs and we experience many miracles....however all do not subscribe to all aspects of what is going on. Anymore than Catholics subscribe to pedophilia or approve of Priests who sin.
Plus there is the “perception” that not enough scripture is taught in the RCC Church as well. But there have been efforts to get that corrected over the years.
