So I threw myself on the grenade....|
"High-church" tends to mean, in Anglican circles, a branch of the church that likes ritual but isn't very concerned with the theology. They are rather looked down on by ACs.
The usage is as much American as English, though it is comparatively specialised. When I was going to Johns Hopkins back in the early 1980s I went to a downtown Baltimore parish which would have been shocked to be referred to as "Protestant".
More importantly from a content of works point of view, the theology is largely identical - Eucharistic sacrifice, invocation of saints, seven sacraments plus a ton of sacramentals, statues and images, etc. and the ritual is similar (if now possibly more traditional than at Rome). The major differences are regarding papal authority. From that point of view SFF from A.C. sources would be largely indistinguishable from that from R.C. sources.
