The Church cannot teach error, because she was founded by Jesus Christ
The Church has no fear of being on the “wrong side of history”, for her Bridegroom is seated at the right hand of the Father.
There are often strident demands, coming from both within and outside the Church, that she change her teachings to conform to modern notions. Given our era’s preoccupation with sex, many of the demands for change involve related issues: homosexual acts, same-sex “marriage,” adultery (particularly divorce and “remarriage”), premarital sex, contraception, and abortion.
