If there’s anyone who plays a very strong influence on how people see same-sex marriages, it would be the Catholic Church. Just like any major religion in the world, this is something they have a strong emotion against. As such, it is important to know why they treat it in this manner instead of just wondering why they have a very high vindication for it.
The biggest reason why the Catholic Church is not Pro-Gay Marriages is because it has a very high regard for both marriage and human sexuality. Taking into consideration what the Bible said,
‘So God created man in his own image, in the image of God he created him; male and female he created them’ (Genesis 1:27 NIV),
God created only two genders. Other passages used as reference for this include:
”Haven’t you read,” he replied, “that at the beginning the Creator ‘made them male and female,’ Matthew 19:4
”But at the beginning of creation God ‘made them male and female’” Mark 10:6
After creating man after his own image, God decided that ‘it is not good that the man should be alone; I will make him a helper fit or him’ (Genesis 2:18). This is how God decided to create women, as a companion of man. Based on these scriptures, the Catholic Church believes that God did not create gays.
As for marriage, the Church believes that it is a sacred union in which God’s grace flows to the couple and to their children. Marriage is a holy vocation for Catholics and is only granted to those who have received the sacrament. One reason why Catholics do not believe man should get married to another man is because of a passage in the Bible, which reads
‘therefore shall a man leave his father and his mother, and shall join to his wife: and they shall be one flesh.’ (Genesis 2:24).
Because of how sacred marriage is, the Catholic Church believes that it needs to be treated with respect. Since it sees marriage as basic to a society’s health, it is a public institution that needs to be protected against harm. For them, the act of marriage is not simply a private matter of emotion between two people. Because it is a public institution, it has a direct impact on society.
This is one reason why they prohibit gay marriages. It is simply not a fairness issue. Since they respect the Bible, they follow it.
