The Church says you must not give anybody the resources with which to sin. Only doing it to avoid a worse evil is an excuse. Sin is considered an intolerable evil. It offends God who deserves only love and it merits everlasting damnation. All that is Church teaching.
The Bible that God supposedly wrote has some things to say about being an enabler of sin.
The Second Epistle of John verse 11 states that to wish a heretical preacher a safe journey is a sin and makes you as bad as he is.
To live in sin makes others want to follow suit and is making a public statement in favour of sex outside marriage.
It is a sin for a landlord to rent a house out to people who live in sin. If he did not give them the house they would not be doing what they are doing in his house. He would not be making sure it is possible for them to sin.
The landlord may say that if he does not house them somebody else will so he may as well let them have the house. But you could apply that to theft. The landlord is still an accessory to sin. He would not rent out a house to people who stated they want to do child sacrifice in it for that would make him an accessory to sin so why should it be any different with fornication?
The landlord may say that the law of the land forbids him to discriminate against unwed or same-sex couples. But the Church says that if the law bans going to Church on Sunday or bans the Bible or forbids the Church to say that the weddings of people who were married before but divorced are invalid the law ought to be defied. The law then would be the most dangerous opponent of the Church there is about. To make friends with it or bear with it would be to collaborate in the persecution of the Church and the Church says it comes before the state for it represents God unlike the state. The apostles were all lawbreakers.
The landlord may say that the reason he is not doing wrong is because it is up to them not him to stop sinning. Really? It would be right to give a person a knife when they say they want to slaughter an enemy if it is.
It is clear then that the Christian Church has to force its morals on other people who dispute its sexual morality. There is no way out.
An employee who has been defrauded in his wages might believe that it is right to steal from his employer. But the Church says this behaviour should not be assisted in and you can’t justify assisting on the basis that the person believes it is right. There is no way then the Church can state that the landlord can allow the persons to have a house with which to sin with and the Catholic Church is well-known for ordering pharmacists not to stock condoms and has banned some from communion for that reason.
The landlord cannot say it is none of his business if the people wanting to be tenants are going to live “immorally” in his house for if the Church is right that the family is the backbone of society and the basic unit of the state the landlord would be attacking himself for he is a part of society and the state so it is his concern. The only seeming way out of the dilemma is for him to realise that the state can do without the traditional family structure within certain guidelines. But there is no doubt that when God created heterosexual marriage he was denying this. If you believe in God, you have to believe that the landlord should discriminate and married people should have the rights that come from being a couple.
No legal protection or rights should be given to same-sex/common law relationships if the Christian faith is true.
Thank goodness it is not!
