Firstly what i learnt during the Indoctrination day service is that the house of God is the church of the living God. 1timothy 3:15 talks about it and also inside the house of God we are to obey the law and commandments of God.
Secondly i learnt that as christians we should go into the world and make disciples of all nations, baptising them in the name of the father. We should baptise them in the house of God not in the house of men. Matthew 28:19
Thirdly i learnt that the church is the body of Christ and Christ is the Head of the church,so that means we are joined with Christ in one body. See scripture reference on Ephesians 3:6, 1corithians 12: 12-27.
Lastly i learnt that we should not use the name of the Lord in vain. When we take the Lord's name in vain,He becomes angry with us because he is the God of the universe,so we should fear and honour his holy name. Exodous 20:7
