Why Are Catholic Priests Not Allowed to Marry? Is Marriage Sinful or Is Celibacy in the Bible?

1. Is Celibacy in the Bible?

One of the most common challenges Catholics face, especially in conversations with Protestants and non-Catholics, is the question of priestly celibacy.

The argument often begins with Genesis 1:28:

> "Be fruitful and multiply, and fill the earth, and subdue it."


Many claim that since Catholic priests do not marry, they are disobeying this command to “be fruitful.” But is that the full story?

The truth is, both marriage and celibacy are biblical — and both are gifts from God.


The Apostle Paul, in 1 Corinthians 7:6-9, gives a crystal-clear teaching:

> "I say this by way of concession, not of command. I wish that all were as I myself am. But each has his own gift from God… To the unmarried and widows I say: it is good for them to remain single, as I am. But if they cannot exercise self-control, they should marry; for it is better to marry than to burn with passion."

Here we see that:

A. Celibacy is a choice, not a command.

B. Paul himself was unmarried for the sake of the Gospel.

C. Marriage is holy — but so is virginity.

D. Each calling is a gift (Greek: charisma) from God.

2. Early Church Practice of Celibacy

It might surprise some to know that celibacy is not a “new invention” of the medieval Catholic Church.

From the earliest centuries, even married clergy practiced continence— abstaining from marital intimacy after ordination — in imitation of Old Testament priests who abstained before entering the sanctuary (Exodus 19:15).

Council of Elvira (305 AD): Forbade clergy from conjugal relations.

Council of Carthage (390 AD): Reaffirmed the practice for all ordained ministers.

This was rooted in the idea that the priest, who touches the Body and Blood of Christ, must be set apart entirely for the Lord.

3. When Priests Could Marry – and the Problems That Followed

Historically, Catholic priests in the West were once allowed to marry, especially between the 8th and 11th centuries. Many served faithfully, but over time, serious problems emerged.


Priestly inheritance of parishes: Some priests passed down church lands and titles to their biological sons.

Corruption & simony: Sacred offices were bought and sold.

Conflicts of interest: Family wealth often took priority over pastoral care.


By the Middle Ages, the priesthood in some regions looked less like the ministry of Christ and more like a feudal aristocracy.


📜 Pope Gregory VII (Hildebrand) saw the danger.

In 1074, during the Lenten Synod, he issued reforms:

I. Ban on clerical concubinage.
II. Removal of priests who purchased their office.
III. Strict enforcement of celibacy.

4. Celibacy as a Sign of Total Consecration

The decision to make celibacy the norm for Latin Rite priests was confirmed at the Second Lateran Council (1139).

This wasn’t about shaming marriage — it was about:

Freeing priests from family obligations so they could serve the flock fully.

Protecting Church lands from becoming hereditary property.

Imitating Christ, the High Priest, who remained celibate for the sake of His Bride, the Church.


Jesus Himself says in Matthew 19:12:

> "There are eunuchs who have made themselves eunuchs for the sake of the kingdom of heaven. Let anyone accept this who can."

5. Celibacy vs Marriage – Both are Holy

The Catholic Church teaches that marriage and celibacy are both sacred vocations. Neither is superior in dignity, but each serves God in a unique way.

Marriage mirrors Christ’s love for the Church (Ephesians 5:25).

Celibacy mirrors Christ’s undivided mission for the Kingdom.

1 Corinthians 7:37 sums it up:

> "The man who has settled the matter in his own mind, who is under no compulsion but has control over his own will, and has made up his mind not to marry the virgin — this man also does the right thing."


Being celibate is not being “loveless.”

It is a different kind of love— a love poured out for all.

 6. Final Thoughts – A Priest’s Marriage Is to the Church

A Roman Catholic priest does not take a wife because his bride is the Church.

He becomes a father to hundreds, sometimes thousands, of spiritual children.



Celibacy is not about what is “lost,” but about what is “gained”:

* Freedom to go wherever the Gospel calls.

* Undivided attention to the needs of the flock.

* A living sign of heaven, where, as Jesus said in Matthew 22:30, "they neither marry nor are given in marriage."
