There are people apparently respectable who look lustfully at other people and so sin against God and break their marriage vows. All who commit adultery, and who persevere in it, without repenting before they die, will be in danger of hell-fire - as Christ told us.
Heroic people in England and Wales have defended the truths of the Catholic Faith, throughout fifteen hundred years - St. Thomas More and St. Margaret Clitheroe amongst them. In our day, brave witness is necessary if people are to realise that it is wrong to kill unborn babies, and that marriage requires a man and a woman to keep their vows, and live together in charity, open to life, in an exclusive relationship which is life-long.
When a man and a woman are about to make their marriage vows in a Catholic church, Christ is there with all His Saints, to witness the marriage, which is a sacrament of the Church. The saints will celebrate the union, and after the vows, will pray to the Father for the couple; and the Angels also pray.
People forget that the vows or promises they have made in church, in either marriage or religious life or Priesthood, are vows made to almighty God. To break those vows selfishly is to act against God. A special vocation cannot be treated as a merry-go-round, on which people enjoy themselves for a while, but leave when they are bored, or dislike the music or the same views at each turn.
Just as no driver is allowed to risk lives on the road, without having been prepared and instructed, so, no-one making vows in the Church, for marriage or Religious Life, which can affect other lives for a life-time and even for Eternity, should do so without first receiving preparation and instruction by the clergy or by loyal, practicing Catholics, authorised by the clergy.
Catholics who make marriage vows or religious vows and live in love, and chastity, are on a straight road towards Heaven. But all who commit unchaste acts or develop unchaste relationships are causing a disaster for themselves and for any others involved, distressing all onlookers. They halt their progress to Heaven as surely as a lorry, crashed into the central barrier, has halted its delivery of goods.
