"The Church is intolerant in principle because she believes; she is tolerant in practice because she loves. The enemies of the Church are tolerant in principle because they do not believe; they are intolerant in practice because they do not love."-- Pere Reginald Garrigou-Lagrange, OP
When I was small I tried unsuccessfully to explain my vision of the Church, as (the best my inarticulate self could do,) "lots of rules, little enforcement", and why that was just as it should be.
Thankfully, there are brilliant theologians to put things into words.
