According to your 'interpretation' of the Bible, Christ, who was celibate, practiced a "doctrine of demons".
Matt. 19:11-12 - Jesus says celibacy is a gift from God and whoever can bear it should bear it. Jesus praises and recommends celibacy for full-time ministers in the Church. Because celibacy is a gift from God, those who criticize the Church's practice of celibacy are criticizing God and this wonderful gift He bestows on His chosen ones.
1 Cor. 7:7 - Paul also acknowledges that celibacy is a gift from God and wishes that all were celibate like he is.
1 Cor. 7:27 Paul teaches men that they should not seek marriage. In Pauls opinion, marriage introduces worldly temptations that can interfere with ones relationship with God, specifically regarding those who will become full-time ministers in the Church.
1 Cor. 7:32-33, 38 - Paul recommends celibacy for full-time ministers in the Church so that they are able to focus entirely upon God and building up His kingdom. He who refrains from marriage will do better.
Why was Peter married? And most of the disciples?
