Which churches permit same-sex marriage

Answer 1

I cannot speak for all denominations, but many Protestant denominations allow women priests or ministers. The three that most people would know about are 1. The United Reformed Church (including Presbyterian and Congregationalist) that has had women ministers for decades. 2. The Methodist Church that also has had women ministers for decades. 3. The Anglican Church (which includes the Episcopalians in the USA) that also allows women priests, and, in some Anglican churches, women bishops too. The founder Church of the Anglican communion of Churches, the Church of England, has had women priests since the 1990s, and is currently exploring the consecration of women bishops. There are many other churches that have women leaders (eg the Salvation Army) although they are not regarded as 'ordained' in the same sense as the above three churches.

Answer 2

Most denominations do, but there are some restrictions in the Orthodox Churches and the the majority of the Roman Catholic Church. Parish priests in the Orthodox Church may be married, but to become a bishop usually requires celibacy, which is why many begin holy orders as monks, where celibacy is the norm. In the Roman Catholic church, celibacy is usually required as a vow by Canon Law, but not as an article of faith. Therefore, in parts of the Catholic Church, such as the Maronite and other Eastern-rite catholic churches in communion with the Roman church, married priests are allowed. Similarly, already-married Anglican priests that convert to the Roman Catholic faith can become Catholic priests and remain married but not serve as principal parish priests. There is also no restriction on widdowers becoming Catholic priests ( The parish priest at my former Catholic parish was a widdowed grandfather! )
