How old do you have to be to get ordained depends on which path you take. Most online ordination organizations set the minimum at 18. Traditional denominations require more, generally between 23 and 35, because ordination is tied to years of seminary or formation. And being ordained is not the same as being legally allowed to officiate a wedding, which carries its own age and registration rules set by state and local governments.
Online Ordination: 18 and Up
If you want credentials quickly, online ordination is the fastest route, and the standard minimum age is 18. The Universal Life Church and American Marriage Ministries both use that threshold, and it is typical across the field. The process is short: fill out a form, and the organization issues your credentials immediately or within a few days.
Courts have generally upheld the validity of online ordinations. When Utah passed a law in 2001 barring ministers ordained online from performing marriages, a federal court struck it down, reasoning that ordination delivered online is no different from ordination delivered by phone or in person. Online credentials are broadly accepted today, though a handful of jurisdictions still create friction. Some Virginia counties have historically questioned online credentials. If you plan to officiate somewhere unfamiliar, call the local clerk’s office before the ceremony rather than after.
Traditional Denominations: Higher Minimums Tied to Formation
Traditional ordination takes years of education, so the age minimums reflect that investment. The specific number varies by tradition, and some denominations leave the decision to individual congregations rather than setting a rule at the national level.
Roman Catholic Church
Under Canon Law, a man must be at least 25 to be ordained a priest and at least 23 for the transitional diaconate, the step leading to priesthood.1The Vatican. Code of Canon Law – Cann. 998-1165 Permanent deacons follow different rules. Universal Canon Law sets the floor at 25 for unmarried men and 35 for married men, but in the United States the bishops’ conference raised the minimum to 35 for all permanent diaconate candidates, married or not.2United States Conference of Catholic Bishops. Canon 1031, 3 – Permanent Diaconate: Age These minimums are tied to completion of seminary programs that themselves take several years.
Episcopal Church
The Episcopal Church requires candidates for the priesthood to be at least 24, with at least 18 months of formation after their nomination is accepted. Once seminary education is factored in, most ordinations land in the mid-to-late twenties.
Protestant Denominations
Many Protestant traditions handle ordination at the local level, so there is no single denominational minimum. Southern Baptist churches are autonomous on this point: each congregation decides who to ordain and when, with no age floor set by the convention. The United Methodist Church does not specify a minimum age for becoming a licensed local pastor either, though its associate membership track requires candidates to be at least 40 with four years of full-time pastoral service. In practice, most Protestant ordination candidates are in their twenties or older simply because the educational requirements take time to complete.
Being Ordained Is Not the Same as Being Allowed to Officiate
If your reason for getting ordained is to perform a wedding, the age question does not end with your ordaining body. State and local governments control who can solemnize marriages, and their rules can go beyond whatever the organization asked of you. Most jurisdictions require an officiant to be at least 18, and some set the bar at 21.
Many places also require registration before you can officiate. Some counties want you to file your ordination credentials with the clerk’s office in advance. Others simply require you to return a properly signed license after the ceremony, and a few require both. Skipping the registration step can jeopardize whether the marriage is legally recognized. Contact the county clerk where the ceremony will take place well before the date, and ask what documentation you need, whether pre-registration is required, and whether any fees apply.
What Else Matters Besides Age
Age is rarely the only hurdle. Traditional denominations layer on educational, experiential, and character requirements that shape the path far more than a birthday does.
Educational expectations range from a high school diploma for entry-level licensing to a full Master of Divinity for full ordination as an elder or priest. The United Methodist Church, for example, requires progressively more education at each stage, from licensing school for a local pastor to a completed M.Div. for a fully ordained elder. Catholic seminarians spend years in formation that combines graduate-level theology with supervised pastoral work. Even denominations with no formal age minimum tend to have educational tracks that take several years, which functions as a de facto age requirement.
Background checks are standard across most ordination pathways, both traditional and online. Denominations and churches use them to screen for criminal history, particularly offenses involving children or vulnerable adults. Many also require a period of supervised ministry, internship, or mentorship before granting full ordination. These steps exist to test whether a candidate can handle the practical and emotional demands of ministry, not just the academic ones.
Online ordination skips most of these requirements, which is both its appeal and its limitation. If you are getting ordained to officiate a single ceremony, the streamlined process works. If you intend to lead a congregation or serve in chaplaincy, the educational and experiential foundations that traditional ordination provides are difficult to replicate on your own.
