C.S. Lewis described Christianity like a house. He wrote that this House had a long hallway with a variety of doors leading off to different sides. Thinking like this, all Christians at some point stand in the hallway, and some stay there longer than others. But for most, there comes a point where we walk through doors labeled "Catholic" or "Baptist" or the ever popular "Nondenominational." Whether we care to admit it or not, everyone chooses a door. Because "it is in the rooms, not in the hall, that there are fires and chairs and meals." Worship and fellowship happens in the rooms. Study. Rest. Life goes on in those rooms. In the hallway, we’re usually just passing each other by. This isn’t to say there isn’t merit in the hallway though.
…of course, even in the hall, you must begin trying to obey the rules which are common to the whole house.
Because we do share one common house. Not that there aren’t things upon which we differ, or issues which we take with certain styles, but none of that matters provided we are all living in the same house, built on The Foundation, that true and proper Cornerstone. We build our notions of church up on things we prefer rather than Truth.
And above all, you must be asking which door is the true one; not which pleases you best by its paint and panelling…the question should never be: ‘Do I like that kind of service?’ but ‘Are these doctrines true: Is holiness there? Does my conscience move me towards this? Is my reluctance to move to this door due to my pride, or my mere taste, or my personal dislike for this particular door-keeper?’
The first experience with Christ in this world was worship, and those who came to see God Incarnate did not care about the style or location. Worshiping the Christ overshadowed all of their personal preferences. And we forget that.
Crucial to living in the same house together is respect. Respect for those who have chosen rooms different from our own, and respect for those who are still standing in the hallway or just coming in the door.
If they are wrong they need your prayers all the more; and if they are your enemies, then you are under orders to pray for them. That is one of the rules common to the whole house.
