Is celibacy or remaining unmarried required to serve as a "priest" ? First off, there is no "priest" that serves as an intercessor between God and the "common" people, but all prayers and supplications are to be directed to God through Jesus as the mediator or intercessor.(John 14:6; 1 Tim 2:5)
And second, there is no requirement for anyone to remain unmarried to serve in positions of oversight. The apostle Peter was married, for at Matthew 8:14, it says that "Jesus, on coming into Peter's house, saw his mother-in-law lying down and sick with fever", which Jesus cured.(Matt 8:15)
And at 1 Corinthians 9, the apostle Paul noted that all the rest of the apostles were married, saying: "We have the right to be accompanied by a believing wife, as the rest of the apostles and the Lord's brothers and Cephas (Peter), do we not ?"(1 Cor 9:5)
And at 1 Timothy 3, concerning the requirements of an overseer, that he has to be "a husband of one wife", if he wishes to be married.(1 Tim 3:1, 2) Then apostle Paul goes on to explain that the "religion" that "forbid marriage" has ' fallen away from the faith ' (or "one faith" that Jesus established as "the truth", Eph 4:5), "paying attention to the misleading inspired statements and teachings of demons".(1 Tim 4:1-3)
Concerning the first man Adam, Jehovah God said that "it is not good for the man to continue to be alone. I am going to make a helper for him, as a complement of him".(Gen 2:18) Hence, he created Eve as his "helper" and thus became "the mother of everyone living".(Gen 3:20)
And then from Jesus words at Matthew 19, that being married or not is a matter of choice, whereby he states: "Not all men can make room for the saying (of remaining single), but only those who have the gift (of singleness). For there are enunchs who were born that way (unable to fulfill their sexuality within marriage because of a flaw in their sexual system), and there are eunuchs who were made enunchs by men (through castration, such as by the Catholic church on young men to sing in Catholic choirs, called castrati, castrating them from the 12th century forward, but only being acknowledged from 1599 C.E. and were not formally banned until Pope Pius X in 1903 C.E.), and there are enunchs who have made themselves enunchs (through self-restraint) on account of the Kingdom of the heavens. Let the one who can make room for it make room for it".(Matt 19:11, 12)
It was not until Pope Callistus II (pope 1119-1124 C.E.) and 1st Lateran Council in 1123 C.E. that marriage was firmly forbidden for Catholic priests, though a document was written some 800 years earlier for those who wanted to be ordained into the "church" to remain celibate (at the Council of Elvira in 304 C.E.) and of which Pope Gregory VII (pope 1073 - 85 C.E.) tried to enforce, but was forced from the papacy in 1085 C.E. by Holy Roman Emperor Henry IV of Germany and died shortly thereafter on May 25 of that year.
Should this not raise a "red flag" since the religion we follow, we depend on as the door to our salvation ? If it has been exposed as ' speaking lies ' that Paul says at 1 Timothy 4:2, what should this cause a person to seriously consider ? If a person finds out that something is wrong in God's eyes, does not a wise person see the need to throw it away and look for that which is the "truth", for Jesus said that his genuine disciples would "know the truth".(John 8:31, 32)
