I’m in the city right now, at my sister’s house. I can walk up the road, and in less than a mile (1.6 km) I’ll have passed a Methodist Church, Baptist Church, and another Methodist Church. Telling you what Presbyterians believe, would be a little simplistic because there’s more than one Presbyterian denomination. Which one do you want? The Church of Scotland? The Presbyterian Church of the United States of America? The Orthodox Presbyterian Church? I hate to sound mean, but this is the problem with Protestantism, in a nutshell. Even amongst Presbyterians, some denominations allow for abortion, some say that there are exceptions to allow for abortion, and some are pro-life. That’s not getting into doctrinal things that specifically have to do with the Bible and sacraments and whatnot. I can’t answer the question, because there’s no such thing as Presbyterian , there’s a bunch of groups of people that call themselves that, but they don’t have a single, Central, unified Authority, so there’s really no way to define Presbyterian.
