A vocation is a divine call inviting you to become the person God intends you to be. There are many different types of calling and we are called to many different things. When the Church talks about vocation it is concerned with a specific ministry within the Body of Christ.
In the Anglican Church we believe that God loves all of us and has given each of us gifts to use in the Kingdom. God calls each of us to a ministry and it is the Church's role to help discern that calling and where possible nurture it. So, although a calling is a very personal invitation it is nevertheless a gift to the whole Body of Christ (the Church).
It is important to remember that a vocation is not just about ordained or even licensed ministry. It is even more important to remember that because God loves and values each of us equally, one calling is no more important than another - what matters is discernment and your response.
Don't be fooled into thinking that being a priest or deacon is the highest calling. It can be tempting to think that the closer you are to the altar the closer you are to God. In reality how close you are to God depends upon how much time you spend in prayer. There is simply no substitute for talking and listening to your Saviour.
And that's where your vocation begins...
