The mission of the Church can be summed up in the Great Commission:
And Jesus came to them and said: "All authority in heaven and on earth has
been given to me. Go therefore and make disciples of all nations,
baptizing them in the name of the Father and the Son and the Holy Spirit,
teaching them to observe all that I have commanded you and lo, I am with you
always, to the close of the age."
Another way to say this is that the mission of the Church is to reconcile all people with God and each other thru Jesus Christ. Any thing that detracts from this mission is bad. That which furthers the mission is good.
The MDGs are good works. They can be ways of furthering the mission of the Church, but they are not the mission of the Church. I will work with non-Christians in relieving poverty, bringing good news to prisoners, working for justice and peace and other "good works" but only if I can do them in the name of Jesus Christ and only if I can, in some way, further the mission of the Church. The Church is only the Church when she is evangelizing.
Now that does not necessarily mean that we start grabbing people by the shirt and asking if they know Jesus. It does not mean that we need to be overt in our evangelism. A great deal of evangelism is what I call "covert." Evangelism can begin with justice issues. It can begin by working the the MDGs. But at some point it needs to be plain that we are doing this because of what Jesus has done for us and what He can do for them.
The MDGs cannot be a goal of the Church. They are a byproduct of living the Great Commission. The MDGs and any other social justice work are works done because of what Jesus has first done for us. If we make them the goal, we cease to be the Church. If we put them ahead of the Great Commission, we start to worship a false god.
I fear that this is what TECUSA is doing - particularly at Lambeth now. Our church leadership is trying to convince others that theology doesn't matter and that soteriology doesn't matter and that moral living doesn't matter. Only "mission" matters. This is a lie and leads to death because it leads to a false god (see the previous post).
I can support most of the MDGs because they can be great means of brining God's word and the new life that Jesus brings to those who do not know Jesus or need to know him better (which is all of us!).
