Peace be with you Jon,
Excellent question! This is a frequently asked question by both Catholics and non-Catholics. Most of the time it has been my experience that it is used to trap Catholics and attack the Faith. In fact the answer is yes, but one cannot experience the fullness of Christ outside the Church. This is support in many ways:
Age of the Church – 2 millennia
And much more. The Catechism and the Church even support openly that Christ can be found outside the Church. But, the fullness of Christ cannot be found outside of it. This is why we pray for the unification of Christ’s Universal Church at Mass.
