@McTag,
Quote:When we say "was built so that" we are thinking about the intentions of the builders. That's in the past, so it makes perfect sense to hold that thought.
Such narrow thinking, McTag. All thoughts that exist have to be contained by the errant thoughts of one man. Preposterous.
The church was built in the countryside so that believers can / could go there to pray.
The passive has been used precisely because the builders were of little to no importance to the speaker/writer. There is no mention of the builders.
Quote:You'll notice I did not say that the use of "can" would be wrong, but the other sounds better and seems more logical.
You've just proven your contention wrong, in a number of ways.
The church was built in the countryside so that believers can / could go there to pray.
One; COULD isn't a matching past tense that you think is needed. COULD means "so that it is possible for believers to go there to pray whenever they felt like it". It means the same thing as CAN. It's only a little more tentative, formal, deferential, softer, ... .
That sentence could/can be paraphrased as,
The church was built in the countryside for the express purpose of allowing believers to go there to pray.
