Just the opposite my friend.
Protestants in general abide in the simplicity of Christ's message and belief in the redemption of the soul through His blood sacrifice...
Catholicism is steeped in a litany doctrines that not even Catholics are sure they understand.
Nope, you just confirmed my point. "Message" and "belief" are doctrinal references.
Catholicism is steeped in a litany doctrines that not even Catholics are sure they understand.
That's how Protestants view it from the outside, but that's not how Catholics experience it. The kernel of a Protestant service is a sermon expounding on the Scriptures. The kernel of a Catholic Mass is the prayer of the priest and people to the Father through Jesus Christ to consecrate the Eucharist. The sermon is an afterthought (optional except on Sundays and high holy days!), and any doctrinal content to the liturgy (and it's possible there isn't nearly enough) is ... well ... not an afterthought, but certainly not central.
It's funny that you say "not even Catholics are sure they understand". It's a very Protestant thing to say. All human doctrines are a created intellect's attempt to understand an infinite God. From my Catholic perspective, if you -- as a created intellect -- are "sure" you "understand" just about any Christian doctrine ... you almost certainly have it wrong.
And the Orthodox say that that's not nearly going far enough.
