As far as i know sa Christian side not all are actually giving 10% to tithes, it may be below or above or nothing at all. yes same sa Catholic, cgro naa sad jud uban cguro nga mo demand jud ug 10% but if we give or not the better is we share our blessings or what we have to others / church. coz at times when kita na jud ang manginahanglan ang Ginoo mohatag jud ug means for us to fill our needs
