A new law in Hawaii can force churches to make their property available to homosexuals for civil union ceremonies. Under this law, if a church should refuse to allow the ceremonies on their property they could be subject to sanctions or fines. See here. In in its Letter to the Bishops of the Catholic Church on the Pastoral Care of Homosexual Persons, No. 17, the Congregation for the Doctrine of the Faith emphasized the fact that church property should not be used for promoting homosexuality in general or same-sex unions. The CDF said that such activity, "..is contradictory to the purpose for which these institutions were founded" and that such activity would be "misleading and..scandalous."
Dignitatis Humanae of the Second Vatican Council insists that, "The freedom or immunity from coercion in matters religious which is the endowment of persons as individuals is also to be recognized as their right when they act in community. Religious communities are a requirement of the social nature both of man and of religion itself.
Provided the just demands of public order are observed, religious communities rightfully claim freedom in order that they may govern themselves according to their own norms, honor the Supreme Being in public worship, assist their members in the practice of the religious life, strengthen them by instruction, and promote institutions in which they may join together for the purpose of ordering their own lives in accordance with their religious principles.
Religious communities also have the right not to be hindered, either by legal measures or by administrative action on the part of government, in the selection, training, appointment, and transferral of their own ministers, in communicating with religious authorities and communities abroad, in erecting buildings for religious purposes, and in the acquisition and use of suitable funds or properties." (No. 4).
the article notes, "Now churches throughout America await the effects of this dangerous law and the inevitable attempt by homosexual activists to force them to use their property in violation of their religious convictions."
Once again, homosexual activists are attempting to use force to impose their agenda.
