For what it’s worth, I definitely prefer being in a smaller parish than a larger one for the same reasons that most here cite. (For me, I consider a “larger parish” to be 3,000 families with 7-8 Masses each weekend and a smaller parish to be <=500 families with maybe 3 Masses each weekend)
With the exception of the occasional “Youth Mass for Life” type of special event or attending a Papal Mass, I cannot wrap my arms around the idea of Mass in a stadium every week...even if it is augmented by small groups. From my perspective, that seems like what these 10,000 - 15,000 person zeta-churches offers their congregants.
Not condemning it...but I just can’t quite comprehend it.
Assuming God is present, always of course with that proviso, its different tools in the toolkit. Some preachers, some circumstances, some settings, will reach people that others will never reach.
Some are purposed for reaching the masses. Some are purposed for training them and grounding them. Some for the short haul and some for the long haul.
Its my belief that the Holy Spirit will, can at least, lead you to the place that is for you. And at some point in time he may then lead you to get up and move. Its not a criticism of the place you left, it had its purpose, but its time for you to move.
