There seems to be different ideas about what exactly silence is. It seems not a few people include implication with silence, ie unless there is an explicit statement, then there is silence. I am of the view that the scriptures teach explicitly and implicitly and that silence is where there is no implicit or explicit requirement, permission or prohibtion for an action. So implication is not silence. It's when people include implication in silence when the troubles occur. The area of implicit permission is the area where most problems occur. The Bible asks us to do certain things and in asking it gives implicit permission for other things (eg a song book to sing songs, a building in which to assemble, using internet forums to "earnestly contend for the faith") None of these things are explicitly taught by the scriptures, but there are explicit statements that permit them. I would be interested to hear what other people think.

Christians are to "sing", therefore a song book gets everyone on the same page singing the same lyrics so it can be done decently and in order. I do not have all the lyrics memorized, so I need a book. In the end, all that is being done is "singing", a song book adds nothing to singing.
Christians are to meet on the first day of the week, that necessitates a place to meet, whether it be a building, house, tent, shade tree, etc to accomodate everyone that attends.
EDIT: Since disciples are to meet, this implies a place to meet thus gives authorization to have a meeting place. It would make no sense for the bible to imply a necessity for a meeting place but then give no authorization to fulfill that necessity.
In the great commission, Christ commanded the disciples to GO, He did not specify how to go, just as long as they went. They could have chosen to go by foot, chariot or horseback, ship or a combination of any. We today have more options (internet), but in the end, just as long as we "go".
