More similarities than differences?

My SO and I came from different churches both of which is widely perceived to be very different in terms of their philosophies and understanding about Jesus' promises. So, I'd guess it's natural that when my SO and I were in our early courtship days, many concerns perpetually run through my mind.

"How Christian is he?"
"Is he worshipping the true Jesus? Or is He fellowshipping with a Jesus I don't know?"
"Is he someone I can trust to lead me spiritually? Or will I have a bigger than usual struggle in learning to submit to him?"

This struggle is not helped by the fact that within the whole body of class, many different congregations (read churches) have very varied practices and understandings which results in different practices. Adding to this confusion is a number aberrent organisations which also teaches about Jesus but who corrupts the gospel He brings.

However, if my and my SO's experiences together could be any sort of reliable barometer, it does appear that believers who value God's word actually have more important similarities than differences in life applications. So far in our conversations, it appears to include:

1) Worship of God as a matter and response of the heart
2) The purpose of dating/courtship
3) The handling of finances in marriage
4) The place of children in marriage
5) Enjoying God and His gifts
6) The importance of Christian fellowship
7) The intention to honour our parents (without worshipping them.)
and many others (I'm simply listing these from off the top of my head.)

Where we do differ, are (in my opinion) areas of relatively lesser importance, these include:
1) The place of suffering in a Christian's life
2) The figurative vs literal nature of God's blessings and how that manifests itself in our lives
3) The partnership between God's effort and our effort in our sanctification process and how it should actually work out in our lives.

For purposes of determining a person basic doctrinal beliefs, you may find this link: http://www.carm.org/christianity/christian-doctrine/theological-test useful. I remember the time before we date when I had subjected him to this test... keke....

But much more than the model answers a person can regurgitate in answering the question, I guess the heart of the matter, is the matter of the heart. After the foundation of ascertaining wheter the person is in relationship with the right Jesus, it is really about how much he/she reveres the Person, places faith in the promises and seeks (mainly through the bible) the will of Jesus.
