The Catholic church "comes with a lot of trimming". If you are used to pomp and circumstance - vaulted ceilings, high platforms, images towering above you the sense that you are in a great awesome temple - with high holy authorities in charge of the place. The RCC is the place to be.
The rituals, the chanting the ceremony - it is all ""designed" to convince you that the leadership is in charge - this thing is way too big and to complex for you to worry your pretty little head about whether it is actually right or Biblical, and you are "told" that "we are right and everyone else is not even a church they just pretend to BE us".
The RCC teaches that NO other communion but the RC communion participates in fact "the New Covenant". The rituals and chanting are supposed to change bread into God - Mark the soul, free from the quilt of sin. Avail you of heaven --
The Priest has "POWERS" that DO no leave him EVEN if he is "excommunicated". His holy POWERS can save your infant just by a few magic montras said with holy water that HE makes holy!
The more complex, mystical (and yes mythica), ornate the ceremony - the more it "seems like" God is behind it and you are connected to another world and the actual power of God. Even the bread is said to be your CONNECTION to Christ "Christ in you" the grace of Christ being infused in you, the New Covenant taken INTO you, Life IN you -- all based on outward ceremony, form and ritual NO NEEd go to God alone in prayer "unless you want to". No need to study the bible to see what God actually says "unless you want to" because these professionals are taking care of it "for you".
When you compare that to a typical evangelical church - what you actually have? Nothing! If that church is charismatic or even Pentecostal you have anarchy, pandemonium, "the rabble" instead of the "form, the reverenence, the POWER of those WITH magical spiritual powers". How in the world could you be satisfied with that?
If you have non-charismatic service then all you reallly get is the "draw" of the pastor - or the "draw" of contemporary music. And when you think of that "small town church idea" as a substitute for the best known "church" in the world -- with Powerful figures like the Pope and the awesome structures, and the claims to magic powers and rules and family and friends that are totaly sold out culturally and traditionally to that "institution" ... etc - well you really have nothing to compare it to.
