The doctrines are not ours they are God's revelation of Himself to mankind so they are sacred and immutable.
Whatever you mean by mirroring Jesus spiritually I don't know, it sounds like a cliché to me. Continuing Jesus's mission on earth is making know God's revelation, His teachings throughout the world. This is the mission committed to the Church by Christ.
<You don't know the sorrows that many have had---and you don't care. Only doctrines seem to matter.> That is a sweeping judgement to make since you don't know what I have been through in my lifetime and to accuse me of not caring is disgraceful. Are you so convinced of your own self-righteousness that you take it upon yourself to judge and chastise those with whom you disagree?
People who want to change the laws of God to suit their individual desires are indulging themselves, that is a fact not a judgement.
<When Jesus said, "Father, forgive them for they know not what they do.> Of course He wasn't judging, He was forgiving.
