A couple of things I have been thinking for a long time in addition to what I have already written about ordination.
Sacramental presence is exemplified in the actions of being broken and poured out. Powerful imagery that is enacted daily and remembered in the Eucharist.
The idea of "sacramental presence" is my theoretical framework ("theology of" for you seminarians out there) for Christian ministry. Ordination is, I believe, an essential aspect of this ideal. The ordination ceremony for me was the more like a wedding ceremony than other "life" event including commencements and commissioning services. This is also entirely appropriate. The Roman Catholic church recognizes seven sacraments that track a person's lifespan ((infant) baptism, (first) communion, (pentiential) reconciliation, confirmation, marriage/holy orders-ordination, anointing of the sick or "last rites").
The only sacrament not required of everyone is marriage. For some, the equivalent means of grace is entering holy orders, or ordination. As it goes with marriage, there's always the first date and first kiss, the process of dating and courtship, engagement, the wedding, and then life together in holy matrimony. Ordination should be though of as the wedding--when the union is recognized by the community, including church, family, and friends. The wedding is a highlight in this much longer practice of marriage, as many cultures put on this ritual, and can last about 20 minutes to several days.
A wedding ceremony, however, does not make people fall in love, it doesn't pro-create, it doesn't "make a covenant" happen, and it doesn't require anyone to stay together. But, with it begins the recognition of what is happening. It does provide a means of grace necessary to make all of this stuff happen for a purpose beyond oneself. It celebrates what has and what will happen through this covenant. So, it goes with the act of ordination. This is why I get so upset when people mess with this process.
This whole bit is a response to something who messaged me this morning. Here's the conversation used with this person's permission (this person offered it, I didn't ask).
