My Wife was baptized outside in October in a lake in Massachusetts when it was about 40 degrees out. BUT couldn't join a Baptist Church, because an Assembly of God pastor had performed it.
1 Corinthians 1:12–15 (ESV): What I mean is that each one of you says, “I follow Paul,” or “I follow Apollos,” or “I follow Cephas,” or “I follow Christ.” 13 Is Christ divided? Was Paul crucified for you? Or were you baptized in the name of Paul? 14 I thank God that I baptized none of you except Crispus and Gaius, 15 so that no one may say that you were baptized in my name.
1 Corinthians 3:16–17 (ESV): Do you not know that you are God’s temple and that God’s Spirit dwells in you? 17 If anyone destroys God’s temple, God will destroy him. For God’s temple is holy, and you are that temple.
