Limits begin to operate whenever activities begin to affect or collide with liberties of others or of the public. Religious activities which concern only members of the faith are and ought to be free -- as nearly absolutely free as anything can be. But beyond these, many religious denominations or sects engage in collateral and secular activities intended to obtain means from unbelievers to sustain the worshippers and their leaders. They raise money not merely by passing the plate to those who voluntarily attend services or by contributions by their own people, but by solicitations and drives addressed to the public by holding public dinners and entertainments, by various kinds of sales and Bingo games and lotteries. All such money-raising activities on a public scale are, I think, Caesar's affairs, and may be regulated by the state so long as it does not discriminate against one because he is doing them for a religious purpose and the regulation is not arbitrary and capricious, in violation of other provisions of the Constitution.
