Leaving aside for now all the social aspects of the problem of freedom, and concentrating on the moment of worship, there is no doubt that whatever form of worship is followed in good faith bears the fruit, small or great, of that Spirit of freedom. Having once experienced, in an almost tangible way, the sense of the presence of God in worship, the comfort of his invisible hand which comes to cover our sin, it is good to become absorbed into it, without being distracted by anything at odds with the meditative concentration. All this has nothing to do with the necessarily single focus of the sermon delivered by a preacher, who must have selected a theme, and requires the whole assembly to concentrate on it. In many cases, this is an excellent thing in itself, and certainly valuable for Biblical study - that even Quakers undertake during the week, when and where there is the opportunity.
Silent worship has certain risks and a certain discipline.
Whoever wants to preach must leave that desire at the door. Whoever is too disturbed, and unable to find peace even in the silence of worship, will be uneasy during all that long gathered centering, and may prefer to leave. God certainly accepts the lament of those who do not succeed in offering him heartfelt worship. Finally there is the freedom to remain in silence, and in everyone's safe equality, even the most taciturn of those present finds with pleasure and surprise the courage to speak. And this too is a form of freedom from fear.
